fix: delete local tag before creating for force release (#76)

When using "Force release even if version unchanged", the workflow
deletes the remote tag but not the local tag. This causes the
`git tag -a` command to fail with "tag already exists".

Added `git tag -d` before creating the tag to handle force releases.
