Improve Github Actions Workflow

[apoclyps]

What's Required?

The current test_and_build workflow run's on every pull request.

This should be split into a test workflow and a build workflow so releases are only produced on a merge to master.

See: https://github.com/apoclyps/magic-home/blob/master/.github/workflows/test_and_build.yml

Acceptance Criteria

• build and test should be 2 separate workflows
• build should only run on a merge to master
• test should run on every pull request
