Building with Clang-22 in C++26 doesn't work. #1924
Description
I tried to build the library using clang-22 and C++26 but it seems that the Catch2 version has compatibility issues. I got the following error:
$ conan build . --profile llvm-22

to tell CMake that the project requires at least <min> but has been updated
to work with policies introduced by <max> or earlier.
