ci: release script to use correct v2 tag format

Parent Issue: #109 (closed)

Warning

This MR should not be merged until we have set the release jobs to dry run mode This script should not be run manually or in CI until we have recreated all of the deleted v2.X.X tags.

This release script was built out with the incorrect assumption that v2 module tags should be in the form v2/v2.X.X.

This is incorrect and we should instead be using the format v2.X.X
