[clang-tidy] Correcting fix suggestion in `readability-simplify-boolean-expr` (#178392)HEADmain

When the checker `readability-simplify-boolean-expr` is used on C23
code, where the `bool` type is provided but not `static_cast`, the fixer
suggests faulty code.

```
bool negative_condition_conditional_return_statement(int i) {
   if (!(i == 0)) return false; else return true;
}

/xx/llvm-project/build/../clang-tools-extra/test/clang-tidy/checkers/readability/simplify-boolean-expr-c23.c:323:25: warning: redundant boolean literal in conditional return statement [readability-simplify-boolean-expr]
  323 |   if (!(i == 0)) return false; else return true;
      |   ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~
      |   return static_cast<bool>(i == 0)
```

Let's skip the use of `static_cast` for C code where a cast is not
needed.
