Remove reference to Toggle inlay hints

This simply removes the reference to the `Toggle inlay hints` action after its removal in https://github.com/rust-lang/rust-analyzer/pull/13215.
In fact, this reference is still visible [in the User Manual here](https://rust-analyzer.github.io/manual.html#inlay-hints).
