Subject: [PATCH 2/2] ci: retry apt-get against Azure mirror in
 copilot-setup-steps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #24's failing `copilot-setup-steps` runs (and the integration
runs) all bottom out on the same root cause: `apt-get update` and
`apt-get install` against `azure.archive.ubuntu.com` intermittently
fail with `Temporary failure resolving`. This is the same flake
that PR #29 (ci/apt-retry) addresses for `.github/workflows/ci.yml`.

Wire the same retry helper (max 6 attempts, exponential backoff
with sleeps of 5s, 10s, 20s, 40s, 80s) around both apt-get
invocations in `copilot-setup-steps.yml`:

- `apt-get update` + `apt-get install e2fsprogs kmod` in
  "Install repo tooling".
- `apt-get install linux-modules-extra-$(uname -r)` in
  "Load ublk kernel module".

The helper definition is duplicated rather than factored out — the
two steps are independent shell sessions, so a single helper would
have to live in a separate script or composite action. Keeping it
inline matches the pattern used in `ci.yml`.

This is an additive commit on top of copilot's original change; no
existing commits are amended.
