[release/2.2] pin sympy==1.12.0 and skip pytorch-nightly installation (…

…#1526)

This PR pins sympy==1.12.0 in the .ci/docker/requirements-ci.txt file
Also it skips pytorch-nightly installation in docker images

Installation of pytorch-nightly is needed to prefetch mobilenet_v2 avd
v3 models for some tests.
Came from
85bd6bc
Models are downloaded on first use to the folder /root/.cache/torch/hub
But pytorch-nightly installation also overrides
.ci/docker/requirements-ci.txt settings and upgrades some of python
packages (sympy from 1.12.0 to 1.13.0) which causes several
'dynamic_shapes' tests to fail
Skip prefetching models affects these tests without any errors (but
**internet access required**):

- python test/mobile/model_test/gen_test_model.py mobilenet_v2
- python test/quantization/eager/test_numeric_suite_eager.py -k
test_mobilenet_v3

Issue ROCm/frameworks-internal#8772

Also, in case of some issues these models can be prefetched after
pytorch building and before testing
