Changes to JFrog/maven permissions

Hi everyone,

I did a few small changes to our JFrog permissions (related to [Who should have write access to deploy to our maven repository?])

If you had an admin user, it won’t have access to deploy artefacts anymore. I’m also not using a ‘grant-all’ kind of permission, but I believe I didn’t revoke any permission to deploy that I shouldn’t.

Please let me know if something doesn’t work as expected.
