Description
Hovering over v:
Hovering over its type inlay hint:
When hovering over a variable, the Global link should (probably? it seems confusing) be omitted, since it is the default also omitted from the type.
When hovering over a type inlay hint, links should be inserted just like we do for variable hovers, and defaulted types like Global should be omitted (seems like an opportunity to deduplicate some code too).

Research direction
Start by reproducing the reported behavior for a variable hover and a type inlay hint in rust-analyzer, using the screenshots as the reference. Trace the hover and inlay-hint entry points and compare how links and default types such as Global are rendered. Done means both hover kinds omit the default Global type and type inlay hints include the same links as variable hovers.
