fix(preset): ssh-to-age now uses -version flag instead of SHA hash workaround

ssh-to-age gained a -version flag (prints bare version like "1.2.0").
Replace the old SHA256-hash-of-help-output workaround with a direct
'-version' call. Prepend 'v' prefix so it matches GithubLatest's
"v1.3.0" format for the skip comparison.

Removes the hardcoded versions map and the crypto/sha256 import.
