workflows: use non-shallow git checkout to please setuptools_scm

By default, github ci action checks out with no history. This leads to
warnings in setuptools_scm and may lead to errors in a future version.
This is a pretty small repo too and thus we shouldn't have much if any
drawbacks to pulling all history.
