ci: Add release.yml for changelog generation

[VaclavElias]

This PR is just a preparation for auto generation of release notes. Once merged, it isn't going to do anything yet, till the GitHub Action is updated. I will make a follow up PR(s).

Feel free to rename titles and labels as desired.

Important notes:

• exclude section excludes certain PRs in the release notes, for example from dependabot
• you need to create the labels so the release notes will be catogorised accordingly:
  • ignore-for-release
  • breaking-change
  • new-feature
  • performance
  • fiddling
  • demos
  • documentation
• you must label each PR, which you would like to categorised, otherwise it will appear in the Other Changes section.
• ideally, if the conditions allow, the PRs should be split according these labels 🤣

Other notes:

• Added a new release.yml file to the .github directory.
• Configures the changelog generation for releases.
• Specifies labels to exclude from the changelog, such as ignore-for-release and contributions from dependabot.
• Categorizes the changelog into several sections
