🌱 [backport] workflow pipeline with unit tests

[lentzi90]

Manual backport of https://github.com/metal3-io/baremetal-operator/pull/1770

This adds a unit test workflow and restructures the github workflows so that we run golangci-lint and unit tests first. Only when they have succeded will the pipeline continue with e2e tests. The goal is to conserve resources and avoid running pointless jobs. The commit also removes unnecessary permissions and avoids running the jobs if the PR is a draft.
