These APIs are used by the web IDE.

They need to be on par with git & web access, allowing edits from
maintainers to forks with merge requests that allow access.

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
