Squash commit template
## Problem to Solve
Currently there is no way to enforce a standard squash commit message on merge requests. This means the squash message needs to be crafted by the maintainer upon merge, or the default squash message from GitLab is used.
## Proposal
With the addition of a merge commit template in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/64437, this functionality should be extended to support the squash commit. This would provide a standard way to configure both types of commit messages for organizations.
