Support basic formatting in hint popup for no-restricted-*

[Samuel-Therrien-Beslogic]

I'd like custom error messages set in rules like no-restricted-syntax, no-restricted-globals, no-restricted-imports, @typescript-eslint/no-restricted-imports, etc. to support basic formatting. Namely to have clickable links and support backticks for code:

I'm not sure if this is rather a core ESLint issue, if so, please let me know and I'll re-open over there.

This is currently not possible. Major reason is that VS Code doesn't support messages for diagnostics other than strings. I will keep the issue around but it needs to be supported by VS Code first.

Should probably open, or link to an existing, issue on VSCode's repo then. I'll see if I can find one.
