Wrong docstring for mesh_edge_loss

[m-nez]

/pytorch3d/loss/mesh_edge_loss.py

The docstring currently mentions that:

Each edge contributes equally to the final loss, regardless of
numbers of edges per mesh in the batch by weighting each mesh with the
inverse number of edges.

Which is wrong. Edges of meshes with relatively many edges have small weights.
It should be:
Each mesh contributes equally to the final loss, regardless of
numbers of edges per mesh in the batch by weighting each mesh with the
inverse number of edges.

Yes you are correct! The language here is confusing. The code is the source of all truth! Thank you for bringing this to our attention! I will add a diff to fix this!
