ci: release pipeline with cross-arch builds

[dancoombs]

Describe the feature
Build a release pipeline that:

1. Runs release level testing
2. Increments the version
3. Publishes a new CHANGELOG
4. Builds docker containers for cross-arch
5. Uploads docker containers

This should be done automatically from the release/* branches upon branch creation (major/minor versions) or new merges (only fix versions) or manually.

cross-rs/cross#724

There seems to be an issue when running cross in conjunction with build scripts, a long running issue that is yet to be solved. I am going to try an alternative or manual building of respective platforms

Mostly complete, just need to include binary gpg signatures like reth does
