Add more tutorials on how to make editor and inspector plugins

[Shadowblitz16]

Describe the project you are working on: Rougelike

Describe the problem or limitation you are having in your project: I want to learn how to make custom language plugins for the built in script editor and inspector layout plugins however there aren't many tutorials on plugins

Describe the feature / enhancement and how it helps to overcome the problem or limitation: I suggest a whole section in the docs be dedicated to something like this ranging from very easy plugins to advanced ones.

Describe how your proposal will work, with code, pseudocode, mockups, and/or diagrams: NA

If this enhancement will not be used often, can it be worked around with a few lines of script?: yes, NA

Is there a reason why this should be core and not an add-on in the asset library?: there needs to be more tutorials on advanced topics such as these so that people can help improve godot

There are already tutorials about creating editor plugins here: https://docs.godotengine.org/en/latest/tutorials/plugins/editor/index.html

That said, keep in mind we're moving away from step-by-step tutorials in favor of a reference manual. This means we most likely won't extend the section with step-by-step tutorials (such as "how to create a terrain plugin"). In other words, we'd prefer to focus on quality over quantity.

Anyway, I'm closing this proposal since documentation requests are off-topic for the Godot proposals repository. If you have other pages to request, create an issue in the godot-docs repository after searching for duplicates.
