Unable to generate Vulkan 1.3 with GLAD2
Using GLAD2 as CMake project.

Adding its  `cmake` subdirectory and running command `glad_add_library(glad2_vulkan REPRODUCIBLE STATIC LOADER LANGUAGE C API vulkan=1.3)` fails with quite some hefty error message ending with `ValueError: Unknown version 1.3 for API vulkan (specification: vk)`.

Command `glad_add_library(glad2_vulkan REPRODUCIBLE STATIC LOADER LANGUAGE C API vulkan=1.2)` finishes without issues.

Looking at the web version hosted at https://gen.glad.sh/, it should be possible I believe in some way to use it or no?
