Deploy failed action on PR from a forked repository

[marcalexiei]

I'm opening an issue to avoid posting off topic content on #17 and because I have the same error on #18

Regarding https://github.com/tjosepo/ror2-editor/pull/17#pullrequestreview-2273980836

Deploy to Firebase Hosting on PR workflow failed with an error:

Input required and not supplied: firebaseServiceAccount

---

I think the error cause is that Github does not provide secrets when a PR is opened from a forked repository:

If you go on https://github.com/OWNER/REPO/settings/secrets/actions On the second paragraph it says:

Anyone with collaborator access to this repository can use these secrets and variables for actions. They are not passed to workflows that are triggered by a pull request from a fork.

There is also a opened issue about this problem on Firebase action-hosting-deploy repository: https://github.com/FirebaseExtended/action-hosting-deploy/issues/337

Right now I'm unable to find an alternative solution 😫
