clang-tidy: misc-include-cleaner: Unused includes not removed from .h file

[JanMatCodasip]

In the attached example, unused includes #include <stdio.h> and #include <inttypes.h> are not removed from number_generator.h.

These are the steps to reproduce:

# Extract the attached archive
tar xvf test-includes.tar.gz
cd test-includes

# Build the example program (compilation database is also created in the process)
mkdir build && cd build
cmake ..
cmake --build .

run-clang-tidy-18.py -header-filter='-*' -checks='-*,misc-include-cleaner' -fix

# Observe that number_generator.h still contains `#include <stdio.h>` and `#include <inttypes.h>`, despite being unused.

(Note that the attached example as well as the steps to reproduce are identical to issue #113926.)

Thank you.
