Is your feature request related to a problem? Please describe.
I'm working on integrating CrowdIn with a project using "changesets". I'd like to run a script that adds a file to be committed alongside the translations.
Describe the solution you'd like
A before_commit_script option in the action for some arbitrary bash code to be run before files are committed to the localization branch.
Describe alternatives you've considered
I have a different github workflow rigged up but it would be nice to not need an additional workflow.
