Argument injection in `gettreesha()` function in Registrator.jl

Impact

If the clone URL returned by GitHub is malicious (or can be injected using upstream vulnerabilities), an argument injection is possible in the gettreesha() function. This can then lead to a potential RCE.

Patches

Users should upgrade immediately to v1.9.5. All prior versions are vulnerable.

Workarounds

None
