chore: upgrade GitLab

[pameladelgado]

Upgrade GitLab to the newer major version 15

[pameladelgado]

GitLab charts had to be modified to delete some deprecated configuration

Running handlers:
There was an error running gitlab-ctl reconfigure:

Removed configurations found in gitlab.rb. Aborting reconfigure.


Removals:
* gitlab_rails['lfs_object_store_direct_upload'] has been deprecated since 14.9 and was removed in 15.0. Starting with GitLab 15.0, only direct uploads will be permitted deprecating this configuration key.
* gitlab_rails['lfs_object_store_background_upload'] has been deprecated since 14.9 and was removed in 15.0. Starting with GitLab 15.0, only direct uploads will be permitted deprecating this configuration key.

@wesjdj @aledegano I'm assuming this can be closed?

[aledegano]
