[CK] Dockerfile: auto-discover latest TheRock nightly tarball
 (#6972)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Motivation

Our docker containers with `--build-arg compiler_version=therock` should
have the latest nightly build of TheRock in `/opt/rocm`. When I looked
for `rocm_kpack` and other `kpack` artifacts, they were missing, and I
realized we had pinned the version by date. Instead, we should look for
the most recent linux-multiarch tarball.

## Summary
- Auto-discover the latest TheRock nightly tarball at Docker build time
instead of pinning a stale URL (previously hardcoded to a Feb 2026
nightly that predates kpack)
- Logic is to `wget` the directory, and identify the latest tarball
(alphabetically sorted by YYYYMMDD in filename).
- Support manual override via `--build-arg TARBALL_URL=...` for pinning,
and `--build-arg TARBALL_PATTERN=...` for selecting a specific arch
variant
- Fix sccache download URL: `/releases/latest/download/` was redirecting
to v0.15.0 but the filename referenced v0.14.0, causing a 404

## Test plan
- [x] Verified tarball discovery logic resolves to
`therock-dist-linux-multiarch-7.13.0a20260430.tar.gz`
- [x] Built Docker image locally with `--build-arg
compiler_version=therock`
- [x] Confirmed sccache installs successfully with the fixed URL
- [ ] Verify CI pipeline builds with the updated Dockerfile
