Upgrade to Rails 8

[coalest]

Doesn't resolve any issue.

Description

• Upgraded rails from 7.2.2 to 8.0.1
• Upgraded filterrific to be compatible with Rails 8
• Upgraded paper_trail to be compatible with Rails 8
• Added a workaround that fixes a Devise issue causing tests to fail with rails 8
• Migrate from annotate to annotaterb because annotate doesn't support Rails 8 and it is abandoned

Type of change

• Dependency update (shouldn't affect users in theory)

How Has This Been Tested?

I did some light testing locally, and all the tests are passing. But we probably want to test this a little more thoroughly and in staging too.

I think we discussed this in the planning meeting a few weeks back and were deliberately going to wait for a while before going forward with Rails 8. @dorner - does that match your recollection?

[dorner]

I think that was for Ruby 3.3 / 3.4. Rails 8 should be safe to update. I'll take a look.

[dorner]

Should be safe to update filterrific now.

@dorner I don't know enough about Rails 8 to intelligently comment -- but given the potentially large number of first time contributors from Scale, and that this feels like a "we should exercise most things" kind of change, I suggest we postpone merging it until next week.

@dorner The annotate gem wasn't working with Rails 8, and upon investigation it has been abandoned. I migrated to the recommended replacement annotaterb. The main difference being it uses a yaml file for configuration, hence the changes seen in this PR
