consider changing checkout to avoid pulling the whole repository

[freddyrios]

      I had to change the checkout to pull the whole repository to get MinVer working again. 
      This is because the checkout action would otherwise not pull the tags.

See actions/checkout#448

Not sure how much we gain from this, but the original issue above was fixed with this PR actions/checkout#579 (in main). We don't need the whole repository for versioning, but we might still want a good amount of commits to be pulled. This is because when doing prerelease builds minver creates a version based on the commits since the last tag.

Before we push this we should do a tagged build first though, as we already have too many commits since the last tag.
