feat: enable shorthand vX tags inherited from latest version

[HassanBahati]

Currently to use the action you need to define the full version version eg v1.0.0 resulting into invertase/firebase-emulator-action@v1.0.0.

This PR enables usage of vX where X is any major release tag. Resulting into, for example; invertase/firebase-emulator-action@v1

I have tested out this approach via custom-short-hand-tag.yaml for HassanBahati/demo-script-action@v1

I think that should do it

I've never made an annotated tag (-a) but -f looks like the way to push that semver major tag up along the releases to the current code, so +1

       -a, --annotate
           Make an unsigned, annotated tag object

       -s, --sign
           Make a GPG-signed tag, using the default e-mail address’s key. The
           default behavior of tag GPG-signing is controlled by tag.gpgSign
           configuration variable if it exists, or disabled otherwise. See
           git-config(1).

       --no-sign
           Override tag.gpgSign configuration variable that is set to force
           each and every tag to be signed.

       -u <key-id>, --local-user=<key-id>
           Make a GPG-signed tag, using the given key.

       -f, --force
           Replace an existing tag with the given name (instead of failing)

basically I used the -a flag to be able to add an annotated tag object to hold metadata, for this case the message. But doesn't really add more value beyond that.

@mikehardy would recommend getting rid of the annotation and have it as simple as;
git tag -f ${{ steps.get_version.outputs.major_version }}
