Handle git errors when cleaning up MR refs

See merge request gitlab-org/gitlab!50250

Access `resolved_on_default_branch` via attribute reader

See merge request gitlab-org/gitlab!50381

Gitlab::Git::Repository::GitError and Gitlab::Git::CommandError
errors can get raised when trying to cleanup MR refs. This will
result to the worker being retried and move to dead queue when
failed after the retry limit.

We don't need to retry in this case as the job will be scheduled
again when picked up by `ScheduleMergeRequestCleanupRefsWorker`
that runs every minute via sidekiq cron.

In order to understand how are users are using the view file by
file feature, we need to track:
- How many users viewed MRs file by file
- How many MRs are being viewed file by file
- How many MRs are being viewed

This is tracked on each request to `diffs_batch.json` since that's
when we show the file by file controls.

Revise Protect documentation

Moving Container Security docs and adding steps
that explain how to set up Container Security.

We don't need to pass the `report_data` and `report` objects around the
method as they are now attributes of the parser instance.

Previously we were instantiating the parser objects without passing any
initialization arguments. Because of this, we were passing the report
and the JSON text to the parse method and all the other utility methods
which was causing inflation on method signatures.

By just passing the report and the JSON text as the initialization args
to the instances, we can avoid passing them in between utility methods.
