Update release process docs for new Versions menu
Updates documentation on how to deploy a new Docs site release now that the Versions dropdown is dynamic.
Changes:
- As of !2808 (merged), only one MR is needed to update the Versions menu, so this removes steps for creating MRs for each older online version.
- Removes the now-deprecated rake task for creating MRs for older versions.
- Adds a step for updating
content/versions.json
- Updates the release checklist template
