Use PyTorch cache key in extra-cache-key action field for dependency installation (#5318)

Now the PyTorch dependency cache depends on the PyTorch cache itself,
not just its version, which should fix the situation when an
old/incompatible cache is used.

This should fix `RuntimeError: operator torchvision::nms does not exist`
error.

E2E accuracy CI:

(`Install torchvision package` step works now)
