Insufficient repository fetch-depth for action workflows (#109)

The GitHub action workflows [1] using the `actions/checkout` action [2]
to fetch the repository that triggered the workflow. However, by default
only the history of the latest commit was fetched which resulted in
errors when wand tried to extract repository metadata information like
the amount of commits ahead of the latest commit. As an example this
can be seen when running the `bootstrap` command in the `test` job of
the `ci-go` workflow [5] which failed with an `object not found` error
because the history only contains a single commit.

To fix this problem `action/checkout` provides an option to fetch all
history for all tags and branches [3] which is now used to prevent
errors like this in the pipeline.
