Update more pins to IREE version 3.1.0rc20241220.

[ScottTodd]

Not sure why I overlooked these in #721.

Edit: oh, the other pins are iree-3.1.0rc20241220 git refs. These are Python package pins.

Commit range: iree-org/iree@iree-3.1.0rc20241204...iree-3.1.0rc20241220

Eh? These are new errors: https://github.com/nod-ai/shark-ai/actions/runs/12604999588/job/35132936581?pr=746#step:7:479

tests/apps/sd/e2e_test.py:236: UnboundLocalError

Previous errors were timeouts waiting for the server to start: https://github.com/nod-ai/shark-ai/actions/runs/12603905601/job/35129849728

Will retry to job to see if that is a consistent change in behavior...

[ScottTodd]

Failure is sticking. The test has a bug - it is swallowing the error and trying to continue:

shark-ai/shortfin/tests/apps/sd/e2e_test.py

Lines 233 to 236 in d42cc29

	except requests.exceptions.RequestException as e:
	print(f"Error sending the request: {e}")
	return imgs, response.status_code

The real error is above in the logs:

Error sending the request: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
FAILED

[ScottTodd]

also seeing those errors on main though? https://github.com/nod-ai/shark-ai/actions/runs/12605515177/job/35134273559

argh... I can't make any changes with confidence while there are failures on main x_x
