Windows build instructions should suggest enabling long paths

(I'm not very familiar with Windows, so maybe I'm doing something wrong here)

I placed the project near the root of my "dev drive" on Windows, but while recursing submodules, I got a bunch of errors like this:

error: unable to create file output/polygon-with-two-holes-outside-exterior-ring/-3.92212,40.2246,-3.30688,40.4842,simplify_distance=8,strictly_simple=1,fill_type=1,mpu=0,par=0.geojson: Filename too long

It seems Windows has a feature, disabled by default for backwards compatibility with MS-DOS (!), to remove the 256-char restriction on file name lengths. This should probably be documented in the windows build guide here: https://github.com/maplibre/maplibre-native/blob/57f42d92302963e21c37601bc6f0e5bf4a4d48df/platform/windows/README.md

Beyond that change, I also had to git config --system core.longpaths true

I don't know much about Windows either, maybe @tdcosta100 can clarify.

Yeah, this is pain in ass, I will change the command in the documentation to include the core.longpaths = true switch, just like we do with the Windows CI. Doing that removes the need to make the setting global, or changing the Windows configuration.
