feat: show latest changes in releases

This should show the latest Changes in the CHANGELOG.md file when creating a new release.

For now it only shows "Automatically created new release".

It is running 'awk '/^## [/{n++} n==1' CHANGELOG.md' which extracts the latest changes. Note: I only tested the command on my linux machine, worked.
