Is your feature request related to a problem? Please describe.
I try to sign my commits with the 'x509' method, but I get the error message:
commit error:
sign builder error: Select signing method 'x509' has not been implemented
Describe the solution you'd like
It would be nice, if signing commit messages next to 'ssh' and 'GPG' with 'x509' would work, also.
Describe alternatives you've considered
My alternative, unfortunately, is to use other tools which support signing with the 'x509' method
Additional context
This is the method used in my company, so I can't use the other signing methods here.
