Modularize workflows. Remove 'ssb-bip' profile

[mallport]

Lots of changes here, heavily inspired from dapla-team-api:

deploy.yml: Generic workflow for deploying to NAIS
build.yml: Runs on every pull request and pushes to main. If the commit is in the main branch, builds and pushes to AR and deploys to the NAIS test cluster
release-docker.yml: Runs when a new release is published. Builds and pushes the application to AR, and deploys to the NAIS production cluster

New changes in fac5a3a:

Modularize even further, removing the workflow for building and pushing artifacts when releasing and instead sharing that logic.

New changes in 11c4cd9:

Don't publish the release - instead, run mvn release on the release branch, and open a PR with the changes. The intent is to manually merge this PR and publish the release draft, which kicks the can to the workflows for build/deployment

we should have an action which publishes a draft release when PRs from the 'release' branch is merged to master
