Use typedef definition as inline hint

[TheLazyCat00]

Imo this should not expand to the whole raw definition, it should just be List<Widget> (or at least be configurable in the lsp settings). This issue is related to #39332. Notice that this issue not only occurs with records, but also typedefs.

Btw the Vector2 isnt even a vector, it should be Dimension2<Pixel>, but the lsp just shows the "lowest level" definition and all the meaning gets lost in the process.
