ci: Add Neuron to the distcheck matrix

Extend the PR CI test matrix to include a Neuron build. We don't really
need to install the Neuron runtime since we don't use NRT symbols
directly, but mimic'ing a typical deployment where that's available is
easy and also helps catch any NRT-specific version requirements we might
add.

Same runtime as before as the runners for the matrix get kicked off in
parallel.
