Description

Commit hash with only numbers appears to violate semver. I wasn't able to confirm it was due to the numbers, but the next attempt succeeded as expected with no changes. That version was: 0.0.0-pr.7.1.f4c705a. I'm assuming it's due to the commit 0137094 being only numbers?

Repro Steps/Link

Try publishing a package with only numbers in the commit hash: 0.0.0-pr.7.1.0137094

        It ended with this exit code:
