fix: use --force flag with git fetch --tags to avoid tag clobber error (#27)

When a workflow is triggered by a tag push, the tag already exists
locally after checkout. `git fetch --tags` then fails with
"would clobber existing tag" for that tag. Adding --force allows
the fetch to overwrite the existing local tag.
