Cluster stack releases using hash mode are displayed wrongly in clusterstack status

[aniruddha2000]

/kind bug

What steps did you take and what happened:
Creating a clusterstackrelease with hash mode. It will show up in "usable" and "latest" in the status of the clusterstack object. However, it will appear with a "-" not with a "." which would be correct.

What did you expect to happen:
We should use the semver version there to reference the correct clusterclasses.
