Prepare release 1.17.0 (#464)

- Generate changelog
- Switch to Github app token.
  - The original GH_TOKEN doesn't exist anymore, but github automatically provisions a GITHUB_TOKEN
  - The `permissions` entry defines that this token is allowed to write (and therefore create releases)
- Removes the apivalidation workflow: This action has been failing constantly and hasn't been maintained in years.
