Nice! Could we have a similar list to the list of conv layers?

Convolutional Layers
--------------------

.. currentmodule:: torch_geometric.nn.conv

.. autosummary::
   :nosignatures:
   :toctree: ../generated
   :template: autosummary/nn.rst

   {% for name in torch_geometric.nn.conv.classes %}
     {{ name }}
   {% endfor %}

there are too many conv modules, if list all the details, i think searching will be inconvenient.

Wdym? nn.attention has 4 layers:

$ git grep "class " torch_geometric/nn/attention/
torch_geometric/nn/attention/performer.py:class PerformerProjection(torch.nn.Module):
torch_geometric/nn/attention/performer.py:class PerformerAttention(torch.nn.Module):
torch_geometric/nn/attention/qformer.py:class QFormer(torch.nn.Module):
torch_geometric/nn/attention/sgformer.py:class SGFormerAttention(torch.nn.Module):

misread it to expand all the conv modules haha
