libinput docs have a big `_static` directory

When I checkout wayland.fd.o git repo, it takes almost 1 GB plus the 177 MB for the .git/ directory.

libinput/ directory takes 724 MB.

libinput/doc/1.17.1/_static/ is 8 MB, of which 7.3 MB is in fonts. The _static directory is present in directories 1.12.0 .. 1.17.1, estimatedly taking 240 MB.

api/ directory used to be 2+ MB until version 1.16.5.

Maybe there is something to optimize here in disk space consumption?
