Feature: identify Inlay Hints text (e.g. info in tooltip)

<!-- ⚠️⚠️ Do Not Delete This! feature_request_template ⚠️⚠️ --> <!-- Please read our Rules of Conduct: https://opensource.microsoft.com/codeofconduct/ --> <!-- Please search existing issues to avoid creating duplicates. --> <!-- Describe the feature you'd like. --> Enhancement Proposal: Some way to identify that a given chunk of text is `inlayHints` and not actually present in the document being edited. Maybe a small help (?) or info (i) icon in the tooltip which explicitly identify this text snippet as a non-code inlayHint and how to disable it. Perhaps something like: >This is an inlayHint provided by the [whatever] vscode extension. See Editor > Inlay Hints (`editor.inlayHints.enabled`) in settings for more. inlayHints are enabled by default and inject text inline into the visual editor -- feels like it'd be helpful to breadcrumbs for how to disable them. As novice Rust user, I recently mistook the inline text provided by rust-analyzer as actual code. After going through dozens of rust-analyzer settings I finally figured out these were "inlay hints".
