Issue Type: Feature Request

git supports commit signing using either GPG or X.509. VS Code apparently supports using both methods, since it uses the signing method that git is set to use (probably by just calling git commit -S).

However, the “Enable Commit Signing” configuration label names explicitly GPG as signing method. If X.509 is set to be used by git, it is also used when commiting using VS Code's git interface, although the user selected “Enable Commit Signing with GPG”.

Renaming the “Enable Commit Signing” configuration label to include both GPG and X.509 would solve this inconsistence.
