As discussed in #412, run steps support a working-directory option for changing the working directory where the command runs.

https://docs.github.com/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsworking-directory

This does not work for uses steps, requiring users to modify their scripts to include a process.chdir.

It would be nice if the action could do that with a working-directory input, avoiding the need to modify a script.
