This restores the merge request commit user fields in import_export.yml
for the import case.

https://gitlab.com/gitlab-org/gitlab/-/merge_requests/73307 dropped
these YAML fields because supposedly the import would fail if the
database columns didn't exist, but I haven't found that to be the
case. I tested with an import with:

1. Project generated in v13.12 that had these columns.
2. Project generated with the latest nightly build.

The import works in either case because we call
`MergeRequestDiffCommit.new` with the sanitized attributes in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/73307.

Based on the discussion in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/72219, these
attributes are needed for **import** but excluded for **export**. I
think Yorick might have assumed that since the code in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/73307 manually
removed these fields, we wouldn't need them anymore. However, without
these attributes, imports were failing to import with an older GitLab
version (e.g. v13.12) because the attributes were sanitized before the
importer got a chance to use them.

application.

Add cluster_id filtering for vulnerabilites graphql query

See merge request gitlab-org/gitlab!71807

This change allows users to filter their runners by type using
tabs directly.

Changelog: changed

Currently the commitsWithoutMergeCommits node list of the graphql
mergeRequest field is not populated if the _source_ project is not
accessible by the user. This is wrong and a break from the behaviour of
the existing REST API.

Fix this in the MergeRequestDiff object's load_commits() function by
populating the CommitCollection from the _target_ project and branch
instead. Otherwise the collection is determined to be inaccessible to
the user.
