⭐ Suggestion

Add a new setting that only shows inlay hints for simple literals. This would include:

  • string
  • number
  • bool
  • regexp literal?
  • null?
  • undefined?

Currently the "typescript.inlayHints.parameterNames.enabled": "literals" setting also shows parameter name hints for function, array, and object literals

I imagine this new setting would be called something like: "typescript.inlayHints.parameterNames.enabled": "simpleLiterals", although better names welcome

Research direction

Start from the existing typescript.inlayHints.parameterNames.enabled setting and its current "literals" behavior. Trace how parameter-name hints are classified for string, number, bool, regexp, null, undefined, function, array, and object literals, then add coverage showing that the new setting includes only the intended simple literals.
