Migrate to github actions

[romgrk]

We should also check if we want to use github releases instead of amazon s3 buckets.

Tasks:

• [x] GHA config
• [ ] Cache apt packages
• [ ] Cache npm modules?

If someone (else than me) is reading this and has knowledge about github actions caching I have questions. Mainly why does it feel like the cache is making things slower?

Caching disabled for now, may be reenabled in the future.
