Migrate LFS from GitLab to Artifactory

[bilke]

Our Artifactory at https://ogs.jfrog.io/ allows non-authenticated pushes for git lfs files in contrast to GitLab where user always needed to authenticate which was quite uncomfortable especially for new contributors.

We have no size limit on Artifactory so we should be safe for the future.

Related to #2347.

TODO after merge:

• Switch off git lfs on GitLab to make sure nobody pushes to the old repo

@ufz/members !
I switched off the old GitLab-based Git LFS server. Please rebase your branches on origin/master to get the right lfs server!

If you are working on envinf1 please use a newer git module than the default: https://www.opengeosys.org/docs/devguide/advanced/working-on-envinf1/#introduction
