[hipsolver][ci] Point Windows TheRock build ref to users/dravindr/tr_hipsolver

The Windows build stage was pinned to TheRock SHA e44b42bb (2026-05-20),
which predates the artifact-blas.toml update that adds bin/hipsolver/**
to the hipSOLVER test include list. As a result, the produced Windows
artifact tarball omitted bin/hipsolver/CTestTestfile.cmake, and
test_runner.py failed with
"Test directory does not exist: build\bin\hipsolver".

Align the Windows build ref with therock-ci-linux.yml,
therock-test-component.yml, and therock-test-packages.yml (already on
users/dravindr/tr_hipsolver) so build and test use the same TheRock
state on both platforms.
