We've become aware that sometimes Zuora => Customers => GitLab fall out
of sync. It certain contexts a user will receive a false message stating
their account has been downgraded when in fact we haven't downgraded
them.

This commit ensures that the user is on the Free plan, before displaying
the downgraded message.

This reverts https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40938
because it wasn't actually working when gRPC exceptions were wrapped in
`Gitlab::Git::CommandError` via `wrapped_gitaly_errors`.

A much simpler approach is to strip `debug_error_string` when a
`Gitlab::Git::BaseError` is created. With this change, we have
effectively the same exception strings as we did before the upgrade of
gRPC.

Note that it appears Sentry retains a backtrace of the original gRPC
exception that contains the `debug_error_string`, so if we really want
to look at it the information is still there.

This should solve https://gitlab.com/gitlab-org/gitlab/-/issues/238465.
