Your Godot version: 4.1

Issue description: Right now, if you search for "Rider" on the documentation website, you get the page about how to set it up for engine development before the page about using Rider for game development, without any indication about what it is about.

This also appears to be the case in external search engines, though those are not as directly actionable.

Some ideas, in no particular order:

We could solve this locally by improving the Rider page itself to start with "In this article you will learn how to use Rider to work with the Godot Engine source code..." or something like that;
Show the topic structure in search results, so people see that they will be visiting the "Contributing > Engine Development > Configuring and IDE > Rider" page and be able to better judge if that's really the page they mean to read. This can quickly get visually busy though;
Somehow preface every page under Contributing with a disclaimer. This is heavy-handed and implies that contributing is discouraged, which I don't think might be the right message;
Currently, C# IDE setup is swept under "C# basics" in the manual, which is a bit sneakily titled as it sounds like it's about the basics of C#-the-language, not "basics of using C# in Godot". Maybe have a separate page for environment setup?

The motivation for this issue was this recent exchange on Mastodon and my previous experience having accidentally bumped into the GDScript Grammar and Debugging and Profiling sections, though those are more obviously not what one would want at first glance.
