When linguist was phased out the data we depended on was vendored. This
created some stale data since than, and this commit updates the vendored
file to the file upstream has at 7.11.0. This version number was choosen
as Gitaly will shortly run `github-linguist` at that version.

Than this updated file is used to update the colors in the database, for
records already in the database. About 200 `UPDATE` statements are
executed.

Merge branch '222268-follow-up-remove-dynamic-qa-selectors-from-audit-logs-template-and-make-them-generic' into 'master'

Remove QA selector props from audit logs and make them generic

See merge request gitlab-org/gitlab!42822

The existing QA selectors were in-place due to the process of migrating
the audit events from HAML templates to a generic Vue app. This removes
these selectors and replaces them with hard-coded generic values as the
dynamic values are no longer needed. We can use the generic values very
simply for all the QA testing requirements.

We can also remove the audit_log_filter QA selector as it isn't used
