Zoltan Kochan 0b2f86ee86 fix: render peer dependency issues on strict error (#11450)
Fixes #11439.

When `strictPeerDependencies: true` causes `ERR_PNPM_PEER_DEP_ISSUES`, the peer dependency issues are again rendered inline — using the **same format as `pnpm peers check`** — so users (and CI tools like Renovate) can see what failed without running another command.

The non-strict warning path is unchanged: it still emits the short "Run `pnpm peers check`" hint.

### Behavior

`strictPeerDependencies: true`:
```
 ERR_PNPM_PEER_DEP_ISSUES  Unmet peer dependencies

✕ unmet peer react
  Installed: 17.0.2
  Wanted:
    ^18.2.0:
      react-dom@18.2.0
hint: To disable failing on peer dependency issues, add the following to pnpm-workspace.yaml in your project root:

  strictPeerDependencies: false
```

`strictPeerDependencies: false` (unchanged):
```
 WARN  Issues with peer dependencies found. Run "pnpm peers check" to list them.
```

### Implementation

- Added a new `@pnpm/deps.inspection.peers-issues-renderer` package at `deps/inspection/peers-issues-renderer/`, alongside its data producer `@pnpm/deps.inspection.peers-checker`. It exposes a single `renderPeerIssues()` that emits the flat issue list previously inlined in `pnpm peers check`.
- Removed the duplicated formatter from `deps/inspection/commands/src/peers.ts` and made the `pnpm peers check` command consume the new renderer.
- `cli/default-reporter/src/reportError.ts`: `reportPeerDependencyIssuesError` now calls the shared `renderPeerIssues()` and prefixes the hint block with the rendered output. Tests strip ANSI escapes before substring assertions so they stay correct under `FORCE_COLOR=1`.

Result: a single renderer is shared between the install error and the `pnpm peers check` command — output is identical between the two paths.
