Update links to Rust Reference in diagnostic

Instead of linking to the [old Rust Reference site](https://static.rust-lang.org/doc/master/reference.html#literals), which is severely outdated (Rust 1.17), link to the [current website](https://doc.rust-lang.org/stable/reference/expressions/literal-expr.html) in diagnostic about incorrect literals.
