[clang-doc] template operator T() produces a bad name

[danakj]

This operator:

  template <SignedPrimitiveInteger U>
    requires(::sus::mem::size_of<U>() >= ::sus::mem::size_of<PrimitiveT>())
  constexpr inline explicit operator U() const {
    return primitive_value;
  }              

Produces this docs:

operator type-parameter-0-0
public U operator type-parameter-0-0()

Which could be greatly improved by just saying "conversion operator to type U. But should also include the concept SignedPrimitiveInteger as the conversion is only valid to a matching type.
