Note that signing is **not supported** on `linux` because you cannot sign binary files on Linux and it is not required for binaries to be signed anyway.

says you can't sign on Linux, but I use osslsigncode to sign on Linux. Perhaps this action could be expanded to use osslsigncode to sign on Linux?

If you are open to that idea, I can look into submitting a PR for your review.
