fix: Support `Input::<..>` style to for generic components

before that, we accepted this style `Input<..>` but to be consistent
with Rust syntax this is dropped now.

> For reference, the two ways of specifying explicit type parameters in
> Rust are:
> // for functions
> let _ = foo::<MyType>();
>
> // for structs
> let _ = Foo::<MyType> { ... };
