Gate new container registry features with Gitlab.com_except_jh?

What does this MR do and why?

Closes #410364 (closed)

Gitlab.com? evaluates to true for JiHu GitLab and we have new container registry features that are only available on GitLab.com.

In !116720 (merged), a new check Gitlab.com_except_jh? is added and in this MR, we are replacing the Gitlab.com? checks with Gitlab.com_except_jh? for the new container registry features.

When using the GitlabApiClient, we also do the check #supports_gitlab_api? in addition to Gitlab.com (Gitlab.com_except_jh?).
