[rollout] Set up GH-AW and install shared PR review workflows (#794)
## Summary
This PR sets up GitHub Agentic Workflows (GH-AW) and installs shared PR
review workflows in `pulumi/pulumi-docker-build`.
### Commands Executed
- `gh-aw version` → `v0.56.2` (used as entrypoint)
- `gh-aw init` → ran (`.github/aw/` was not present)
- `gh-aw add
pulumi-labs/gh-aw-internal/.github/workflows/gh-aw-pr-review.md@main
--name docker-build-pr-review --force`
- `gh-aw add
pulumi-labs/gh-aw-internal/.github/workflows/gh-aw-pr-rereview.md@main
--name docker-build-pr-rereview --force`
- `gh-aw compile`
- `gh-aw validate`
### Configuration
| Property | Value |
|---|---|
| AW entrypoint | `gh-aw` (v0.56.2) |
| Target base branch | `main` |
| `prefix_stem` | `docker-build` |
| `gh-aw init` | Ran (was not previously initialized) |
### Changed Files
- `.gitattributes` — added `merge=ours` strategy for
`.github/workflows/*.lock.yml`
- `.github/agents/agentic-workflows.agent.md` — created by `gh-aw init`
- `.github/workflows/copilot-setup-steps.yml` — generated dependency
workflow
- `.github/workflows/docker-build-pr-review.md` — shared PR review
workflow source
- `.github/workflows/docker-build-pr-review.lock.yml` — compiled lock
file
- `.github/workflows/docker-build-pr-rereview.md` — shared PR re-review
workflow source
- `.github/workflows/docker-build-pr-rereview.lock.yml` — compiled lock
file
- `.github/workflows/shared/review.md` — imported shared workflow
- `.github/workflows/shared/plugins/code-review/code-review.md` —
imported shared plugin
### Validation Output
**compile:**
````
⚠ Compiled 2 workflow(s): 0 error(s), 2 warning(s)
```
**validate:**
```
⚠ Compiled 2 workflow(s): 0 error(s), 2 warning(s)
```
### Validation Warnings
Both workflows produced the same non-blocking warning:
```
warning: This workflow grants id-token: write permission
OIDC tokens can authenticate to cloud providers (AWS, Azure, GCP).
Ensure proper audience validation and trust policies are configured.
````
These warnings are expected for the shared review workflows which use
OIDC for cloud authentication and are non-blocking.
