Packaged collection has git related files

[anshulbehl]

roles/k8s_manifests/.git

Files like above should not be packaged in the collection, having that file breaks git status and other commands, and prevents ansible-test from working when that collection is installed.

It looks like the issue is that those .git files are used to track the git submodules that I use in this collection and https://github.com/geerlingguy/ansible-collection-php_roles, since I maintain the roles downstream and package them up in these collections.

I've asked in the linked issue whether this is something that would be able to be ignored in 2.9.x, or if it requires running ansible from devel to build the collection without the .git files...
