Feature: Automatic GitHub release on PR merge

[vb2007]

Description

Create a workflow for automatic GitHub release publishing

• The workflow should get the version from the package.json file
• The workflow should automatically generate release notes & relevant release data

Release types:

• When merging to the main branch, a new major vi+1 version should be published
• When merging to the dev branch, a new vx.i+1 version should be published
  • Merges on dev should be marked as experimental releases
• The version should get specified manually in package.json before merging PRs
  • A unit test could also be made that tests if the version really has been modified in the file
