The workflow creates a GitHub Release Draft as follows:
- Title with a version number parsed from the git ref that triggerd the workflow
- Body parsed from the changelog
- Compiled .elf and .hex files for board versions 3.5 and 3.6
- Python package (as .tar.gz file)
The workflow was tested by adding the trigger
`on.push.branches: [autorelease/v0.5.2]` and then pushing onto
that branch.
