[arnaldo2792]

Description of changes:
Provide 2.x.8586.0 and 2.x.8732.0 Neuron kernel modules. Additionally, update summaries of kernel modules since they were a bit inconsistent with other kernel modules

Testing done:
Launched a inf2 instance, confirmed devices are visible and advertised with the new kernel modules:

bash-5.2# insmod /usr/libexec/neuron/neuron_2x_8732/neuron.ko

I had to re-create the device plugin pod to make sure it used the new driver, then I confirmed it worked:

bash-5.2# /opt/aws/neuron/bin/neuron-ls

not required at all but given changes of this kind, do you think it would be a good idea to make the gpg-key Source1 ?

That's a great call out, let me fix that

Actually, lets punt this, it will get all confusing if I do this in this PR.
