Thanks for the package update, @scowalt

Please have a look at the GitHub actions warnings:
https://github.com/streamlink/streamlink-twitch-gui-chocolatey/actions/runs/5814724283

1. node12 is EOL and gets replaced by node16
2. set-output is deprecated
3. invalid input for the EndBug/add-and-commit@v8 action (using a branch/tag name instead of an explicit commit ID for external actions allows bad actors to potentially hijack the repo and read secret env vars)

Fixed with ab5db99

There's one warning left and it appears to be this issue EndBug/add-and-commit#516
