[hipsolver][ci] Revert TheRock workflow refs to develop's pinned SHA

Restore all four TheRock-side workflow refs to the develop-tracked pin
e44b42bb (2026-05-20):

- .github/workflows/therock-ci-linux.yml
- .github/workflows/therock-ci-windows.yml
- .github/workflows/therock-test-component.yml
- .github/workflows/therock-test-packages.yml

Reverts the workflow ref changes from 71e281c, 17acb08 and
daaa6a4, which temporarily pointed all four files at the paired
TheRock branch users/dravindr/tr_hipsolver.

At the develop-pinned TheRock SHA, fetch_test_configurations.py still
runs the legacy test_hipsolver.py for hipsolver (not test_runner.py),
and math-libs/BLAS/artifact-blas.toml does not include bin/hipsolver/**,
so the new install-tree CTestTestfile.cmake and
apply_test_category_labels() metadata added by this PR remain dormant
until ROCm/TheRock#5490 merges and these refs are bumped to a
main-tracked SHA that contains it. Until then the hipsolver
Linux/Windows test shards behave exactly as on develop.
