Need an option to disable the documentation section on hover

[blastrock]

Is your feature request related to a problem? Please describe.
When I hover some symbol on Dart, I get a documentation section on hover:

I couldn't find a way to disable that section. Note that I don't want to disable the whole popup (which can be done at vscode level), I still need the build errors, the debugger inspections, and even the function prototype. I just want to remove the documentation.

Describe the solution you'd like
A lot of other plugins have an option for that, like:

  "rust-analyzer.hover.documentation.enable": false,
  "html.hover.documentation": false,
  "csharp.referencesCodeLens.enabled": false,

As an example, here's what my config looks like in C#, there's only the full type and a short description appearing:

Is there an option in the Dart extension that I missed? Can you implement one?

There's not currently an option for this, the hovers always include full docs.

Perhaps we should have a tri-state option for this: "Full", "Summary", "None". There's a long-standing VS Code issue about errors being tagged onto the end of the scrolling docs, which means long docs result in a lot of scrolling to see errors when hovering over squiggles so being able to see just the summary might be useful if you don't want to lose the whole doc.

Server work is in dart-lang/sdk@09c1722. We'll need to add the new setting to the package.json so it shows up in the UI.
