build(gen_vimdoc): abort if doxygen version is too old
There have been a few instances where developers got confused as to why their generated documentation differs from the one generated by the CI. More often than not, the reason is that their doxygen version is older than 1.9.0, which is the current minimum version. Having a simple version check will help save future developers avoid this problem.
