What does this PR do?
This PR removes Longformer from the list of ONNX-supported models due to a current limitation in the supported ops in JIT - see issue #15217
This slipped through our unit tests because we didn't include
longformer
in the list of models to be tested.Long term, we'll either need to wait for JIT to support the problematic ops or tweak the Longformer implementation.
