Propose stage assignments for administration pages

What does this MR do?

Proposes stage / group assignments for the following pages:

• administration/auth/smartcard.md - devopsmanage ~"group::access" because it's about authentication (@mjang1)
• administration/compliance.md - devopsmanage groupcompliance because it's about compliance (@mjang1)
• administration/database_load_balancing.md - devopsenablement groupdatabase because it's about databases (@axil)
• administration/object_storage.md - devopsenablement groupdistribution because omnibus-gitlab!4368 (merged) came from there in %13.2. (@axil)
• administration/operations/extra_sidekiq_processes.md - devopsenablement groupdistribution because it's about Omnibus GitLab (@axil)
• administration/raketasks/doctor.md - devopsenablement groupgeo because it's mostly about #20069 (closed) which was added by this group in %13.1 (@axil)
• administration/raketasks/geo.md - devopsenablement groupgeo because it says in the first sentence it's about Geo (@axil)
• administration/raketasks/ldap.md - devopsmanage ~"group::access" because LDAP is about authentication (@mjang1)
• administration/troubleshooting/elasticsearch.md - devopsenablement groupglobal search because it's about search (@axil)
• administration/troubleshooting/group_saml_scim.md - devopsmanage ~"group::access" because SAML is about authentication (@mjang1)

I am open to any of these being wrong. I'm making guesses based on linked MRs and what's on the page.

Author's checklist (required)

• Follow the Documentation Guidelines and Style Guide.
• If you have Developer permissions or higher:
  • Ensure that the product tier badge is added to doc's h1.
  • Apply the documentation label, plus:
    • The corresponding DevOps stage and group labels, if applicable.
    • development guidelines when changing docs under doc/development/*, CONTRIBUTING.md, or README.md.
    • development guidelines and Documentation guidelines when changing docs under development/documentation/*.
    • development guidelines and Description templates (.gitlab/*) when creating/updating issue and MR description templates.
  • Assign the designated Technical Writer.

Do not add the feature, frontend, backend, ~"bug", or database labels if you are only updating documentation. These labels will cause the MR to be added to code verification QA issues.

When applicable:

• Update the permissions table.
• Link docs to and from the higher-level index page, plus other related docs where helpful.
• Add the product tier badge accordingly.
• Add GitLab's version history note(s).
• Add/update the feature flag section.

Review checklist

All reviewers can help ensure accuracy, clarity, completeness, and adherence to the Documentation Guidelines and Style Guide.

1. Primary Reviewer

• Review by a code reviewer or other selected colleague to confirm accuracy, clarity, and completeness. This can be skipped for minor fixes without substantive content changes.

2. Technical Writer

• Technical writer review. If not requested for this MR, must be scheduled post-merge. To request for this MR, assign the writer listed for the applicable DevOps stage.
  • Ensure docs metadata are present and up-to-date.
  • Ensure Technical Writing and documentation are added.
  • Add the corresponding docs:: scoped label.
  • If working on UI text, add the corresponding UI Text scoped label.
  • Add twdoing when starting work on the MR.
  • Add twfinished if Technical Writing team work on the MR is complete but it remains open.

For more information about labels, see Technical Writing workflows - Labels.

For suggestions that you are confident don't need to be reviewed, change them locally and push a commit directly to save others from unneeded reviews. For example:

• Clear typos, like this is a typpo.
• Minor issues, like single quotes instead of double quotes, Oxford commas, and periods.

For more information, see our documentation on Merging a merge request.

3. Maintainer

1. Review by assigned maintainer, who can always request/require the above reviews. Maintainer's review can occur before or after a technical writer review.
2. Ensure a release milestone is set.
3. If there has not been a technical writer review, create an issue for one using the Doc Review template.
