[Feature flag] Rollout of `show_author_on_note`

What

Remove the :show_author_on_note feature flag ...

Owners

• Team: groupproject management
• Most appropriate slack channel to reach out to: #s_plan
• Best individual to reach out to: @smcgivern

Expectations

What are we expecting to happen?

Enabling this flag shows an 'author' badge on issue and MR comments made by the author of the issue or MR.

What might happen if this goes wrong?

There might be a bug (unlikely). More likely is simply that we find this too cluttered visually.

What can we monitor to detect problems with this?

We can just look at the pages 🙂
