disable flasky test in github workflow (meta-pytorch#3528)

Summary:
Pull Request resolved: meta-pytorch#3528

Disabled a flaky test in the TorchRec sequence model parallel test suite to prevent intermittent failures in the GitHub workflow CI pipeline. The test was causing unreliable builds and needed to be disabled until the underlying issue can be properly investigated and resolved.

NOTE: The first CUDA IMA error will cause all following cuda-related tests to fail
