The external_parent_case config linter identifies a class definition as its own parent.

[BigBattleBoy]

Tools (complete and add to the following information):

• HEMTT: 1.14.1
• Operating System: Windows

Description:
The external_parent_case config linter is identifying a class definition as its own parent, which results in the config linter missing some errors and misidentifying others.

Steps to reproduce:

1. Include the following in a config.cpp:

class A {
        class B {
        };
};

class A1 : A {
        class b : B {
        };
};

2. Run "hemtt.exe dev"

Expected behavior:
The config should build without error, as the child class 'b' correctly identifies the parent class 'B' with the correct letter case.

   │           -   ^ parent does not match definition case
   │           │
   │           parent definition here
   │
   = help: change the parent case to match the parent definition
   = try: b


error[L-C05]: parent case does not match parent definition
   ┌─ addons/main/config.cpp:14:12
   │
14 │     class b : B {
   │           -   ^ parent does not match definition case
   │           │
   │           parent definition here
   │
   = help: change the parent case to match the parent definition
   = try: b

Additional context:
If the config is changed to

class A {
        class B {
        };
};

class A1 : A {
        class b : b {
        };
};

then the linter incorrectly misses the case error.
