galaxy.yml: exclude non-collection files from collection build

[dmsimard]

SUMMARY

Files that belong to the git repository such as git, github and
azure pipeline configuration should not be included in the published
collection tarball.

Excluding tests saves on what makes the bulk of the size of the
collection, both in size and number of files.

In aggregate, excluding these files results in a meaningful improvement
which will speed up the installation of the collection and reduce the
size on disk.
