Pin tensorflowjs

[rosbo]

A new version of tensorflowjs has been released and requires tensorflow

= 2.13. We are currently using 2.12 and this is causing a test failure.

Full context in bug.

tensorflowjs test is now passing:

test_version (test_tensorflowjs.TestTensorflowjs) ... tensorflowjs_converter version:  CompletedProcess(args=['tensorflowjs_converter', '--version'], returncode=0, stdout=b'\ntensorflowjs 4.10.0\n\nDependency versions:\n  keras 2.12.0\n  tensorflow 2.12.0\n', stderr=b'2023-09-15 05:08:52.715863: W tensorflow/compiler/tf2tensorrt/utils/py_utils.cc:38] TF-TRT Warning: Could not find TensorRT\n')
ok

There is another unrelated test failure related to pandas. Will investigate on Monday.
