Upgrade upstream ROCm CI from 7.2.0 to 7.2.2
Point the three upstream ROCm workflows at the new 7.2.2 base images
published by ROCm/rocm-jax:
- build_rocm_artifacts.yml: switch the manylinux_2_28 builder image
from jax-manylinux_2_28-rocm-7.2.0:latest to ...-rocm-7.2.2:latest.
- bazel_rocm.yml / pytest_rocm.yml: bump the default rocm-tag from
rocm720 to rocm722 (and the default rocm-version from 7.2.0 to 7.2.2
for pytest_rocm.yml), so the jobs pull the jax-dev-ubu24.rocm722 /
jax-base-ubu24.rocm722 containers.
- wheel_tests_continuous.yml / wheel_tests_nightly_release.yml: update
the rocm matrix entry to {version: "7.2.2", tag: "rocm722"}.
- download-jax-rocm-wheels composite action: bump the default
rocm-version to 7.2.2 to match.
