fetch entire repo to have tags for determining package version

By default the actions/checkout@v2 fetches only the last commit without
any other meta-data including tags. Thus when setuptools_scm attempts
to determine the version from git, it sees no tags, and cannot determine
the version or the distance from the last tag (for dev builds).
