Automated git version fixes (#39637)

Use full length commit sha instead of short prefixes, to improve
reproducibility (future clashes) and guard against compromised repos and
man in the middle attacks.

Abbreviated commit shas are expanded to full length, to guard against future
clashes on short hash. It also guards against compromised repos and
man in the middle attacks, where attackers can easily fabricate a malicious
commit with a shasum prefix collision.

Versions with just tags now also get a commit sha, which can later be used to
check for retagged commits.
