Add step to create release draft and upload zip

[GeckoEidechse]

Uses https://github.com/softprops/action-gh-release to create a draft release and upload the Northstar release zip to it.

I adapted the example found here for Northstar.

Not tested cause not sure how I'd do it with act without modifying releases on this repo...

Also doesn't skip release candidates cause I don't know to adapt the if to ignore version numbers with the -rcX suffix ^^"

I generally work on a separate testing repo for trying out workflows.

Something like startsWith(github.ref, 'refs/tags/') && !contains(github.ref, '-rc') should be a good-enough approximation; you'd need to define a custom step with github-script or something similar if you want it more granular.

Added that in 34eb359b12894d7215a8a0e6d357bc7a71af1c79 and seems to work.

Forked into https://github.com/GeckoEidechse/Northstar and did some testing. Found 2 more issues (missing perms and uploading zips) and resolved them now in 6d90f5f61e8b00553939c5014d5fd89e5a7d420c

For a successful run, see https://github.com/GeckoEidechse/Northstar/actions/runs/4344931842

Note that Thunderstore job failing is expected on the fork as it's missing the auth key to publish to Thunderstore. As there were no changes to that job I don't think it's necessary to test it ^^
