ci: update build workflow to include assets

[FlayaN]

Added a workflow that build and creates a release on the fork repo, will run on every fork push. Not on doodlom repo.

Update the build workflow to also bundle in addons, can be manually triggered like before on forks to easier test new PRs

Example release for this PR:
https://github.com/FlayaN/skyrim-community-shaders/releases/tag/untagged-59d9606a360720ff5014

• Uploads all the zip files (the output from CMAKE option ZIP_TO_DIST)

• Creates a combined zip with all the files in one package (Same files that are copied to output when using AUTO_PLUGIN_DEPLOYMENT)

This allows to easier test a PR before approving it, can also make "alpha/beta" releases easier for posting them on discord in #forums

Thanks for doing this. I'm not sure it is a good idea to do it on all fork pushes. The build itself can eat a lot of ci time and I definitely push a lot just to sync.

Is it possible to trigger it on PRs to the main repo based on some tag a user can add? Or if it starts with feat:? Or maybe it can be simpler and be a workflow trigger and we just manually ask someone to trigger and post a release as part of our PR process. Thinking more, having that may let us build nightlies or something.

I still want this, but can you let me know if we can address some of my thoughts? Even if it's just saying it's not feasible or already did it?

Thanks!

I'll think some more about this flow! Maybe the easiest it to have it manually triggerable like you mentioned...

[FlayaN]

Simplified this PR to update the existing build pipeline instead (Updated main description)! Now also bundles all the addons on the release as well, that then can be triggered by the creator of a PR. I think this is a good starting point that can be extended in the future

Looks good to me.
