Support contributors to show their work more prominently

In order to show contributions made to Eclipse in a release to the world and Eclipse users one currently creates a New and Noteworthy entry at https://eclipse.dev/eclipse/news/, which is also linked from https://eclipseide.org/release/noteworthy/.

These entries are usually very technical and concise. It would be great if contributors could additionally create articles or blog-posts that can describe new features or a group of features more elaborately and less technically if desired or could even cover non-technical topics related to the Eclipse-IDE.

These would be an opportunity for contributors to advertise their work and for Eclipse to show it's activities. The topics should cover the whole IDE respectively the SimRel.

These articles could be published at https://eclipseide.org when the release is published and could for example be shown at or below the 'feature'-tiles. The Eclipse website already has the Newsroom feature, where one can submit an article to be posted at different Eclipse project pages. We could probably re-use the feature for that and only would have to make sure that these articles are shown at a good location (currently I don't see were exactly such article would be shown at https://eclipseide.org), are published at the right time (e.g. exactly at the release date or maybe as a teaser a little bit before, maybe with a banner stating that it's an upcoming feature) and stay for a sufficient time at https://eclipseide.org (if cross-posted to other EF-pages the news might be replaced quicker by news of other projects). For the last point: the articles should probably be prominently shown until the next release, but still should be easily accessible afterwards as one might look at the articles/release notes from a longer period.

If the process is known, we should document it well at a place where contributors find it, for example at https://github.com/eclipse-platform/www.eclipse.org-eclipse

The article content could be for example be inspired by the news article (only in German) that is publish for each release at the heise.de news website, e.g.: https://www.heise.de/news/Entwicklungsumgebung-Eclipse-2025-03-aktualisiert-fuer-C-23-und-Java-24-10313713.html
