Invalid hover and goto on u96 type

[integraledelebesgue]

Hover for u96 type in corelib's circuit_test contains the BoundedInt, which u96 aliases, instead of the u96 itself.
"Go to definition" also points to the original type, not to the definition of u96.

same happens for impl aliases:

// Pow implementation for any algebra.
impl AnyAlgebraPow<A, impl AlgImp: Algebra<A>> of Pow<A> { ... }

// Impl alias for Pow of i32.
impl Int32Pow = AnyAlgebraPow<i32, I32Algebra>;

// do goto definition on Int32Pow usage

I think the expected hover should show something akin to:

path:to::u96
pub type u96 = core::internal::bounded_int::BoundedInt<MINMAX>;

Goto definition, find references and rename also looks to be broken, cc #435
