chore(packaging): set tag length to 7 (grafana#901)

* chore(packaging): set tag length to 7 relied on git approximation before, which causes problems with other parts of the automation. Because we do not need the tag to be strictly unique, but just to identify the latest version, limiting to 7 is fine. If this ever causes problems, raise the limit but make sure to update all other places as well. * chore(packaging): request at least 7 characters Co-Authored-By: Dan Cech <[email protected]>
