Use actions/changed-files instead of jitterbit/get-changed-files

[DropSnorz]

jitterbit/get-changed-files is not anymore maintained and use deprecated APIs

Switch to actions/changed-files or git diff if required.

I am looking to add the same functionality to studiorack-registry
I noticed you were using https://github.com/marketplace/actions/get-all-changed-files instead of https://github.com/marketplace/actions/changed-files

Came here to create an issue, but you beat me to it :)

Hi Kim, thanks for the intent !

I've seen you're working on "hardening" things for studiorack registry. I'll keep an eye on changes 😉
