We were technically already using 22.04 for a bit, it got updated without us noticing since the version was set to `ubuntu-latest`.
Affix the version to 22.04 so that it doesn't get unexpectedly updated again, and update the artifact's zip to reflect the change.
* Download and list artifacts after build
* Add commit hash + file extension to artifact name
* Initial SSH implementation
* Don't build artifacts for PRs
* Fetch endpoint from secret
* Zip artifacts before uploading to CDN
* Use short SHA in archive names
