Documentation: GeometryBasics.mesh docs don't match function signature

[Wizarth]

The documentation for GeometryBasics.mesh function indicates it takes a uvtype keyword parameter, but the implementation takes uv keyword parameter.

Given that all the other keyword parameters are somethingtype, I'd assume it's the function signature that is incorrect.

This seems like an inconsistency. It is probably easier to to fix the docs now. We could add a uvtype and make the uv kwarg a deprecation warning until 0.5 or 1.0. I've rarely worked with UVs so I may be missing some mechanics or some implicit typing here, so let's keep this open for more discussion.

For an additional data point, MeshIO uses exactly the same keyword parameters, except using uvtype vs uv
