Remove the What's new documentation
I intend to remove the What's new documentation. See https://testing.docs.gimp.org/2.10/en/gimp-introduction-whats-new.html.
These document the changes in the last minor version. There are not enough volunteers to always keep this up-to-date, both as documentation and as translations. We could possibly link to the latest version release notes on the website.
Instead of the current what's new, we could highlight the major new features of the last major version update (currently 2.10, in the future 3.0). However, that requires that documentation for those features is written first. Since it makes most sense to link to the documentation pages that describe these features.
