<details>
<summary>Changes</summary>
This reapplies #<!-- -->92957 and #<!-- -->98547 with the following changes:
- We only apply the resolution to CWG1835 in C++23 and later, and
- We issue a diagnostic when its application results in a missing template
keyword that breaks whatever construct that follows the intended template name.
e.g.
```cpp
template<int I>
struct A {
int x;
};
template<int I>
struct B : A<I> {
void f() {
this->A<I>::f(); // with -std=c++20 and earlier: no error
// with -std=c++23 and later:
// error: no member named 'f' in the global namespace
// error: missing 'template' keyword prior to
dependent template name 'A'
}
};
```
Only applying the resolution in C++23 and later conveniently gets around [a bug
in GCC releases prior to
11.1](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94799) that prohibits the
use of `template` prior to the _nested-name-specifier_ in a class member access
expression as the affected versions do not support C++23.
