This reverts commit eff378ca.

Instead of only checking for migrations, we now check for a variety of
files and directories that require a database review. We also include
some steps on how to make sure changes are reviewed.

Fix ArgumentError in GitGarbageCollectWorker Sidekiq job

Closes #49096

See merge request gitlab-org/gitlab-ce!20541

When the Gitaly call failed, the exception handling failed
because `method` is expected to have a parameter.

Closes #49096

Before b46d5b13, we relied on
`Addressable::URI` to parse the username/password in a URL, but this failed
when credentials contained special characters. However, this introduced a regression
where the parsing would incorrectly truncate the password if the password had a colon.

Closes #49080
