🪲 [Fix]: Super-linter can now post PR comment summaries (#308)

Super-linter's inline PR comment summaries now appear when lint errors
are found. Previously, the linter detected issues but silently failed to
post the summary comment, requiring developers to navigate to the
Actions log to see what went wrong.

- Fixes #307

## Fixed: Lint error summaries now visible directly on PRs

When super-linter detects markdown, YAML, or other linting issues, it
posts a summary comment on the pull request for quick feedback. This was
failing with a 403 error because the `Lint-Repository.yml` reusable
workflow's `permissions:` block only granted `contents: read` and
`statuses: write`, omitting the `pull-requests: write` permission needed
by the GitHub Issues API to create comments.

The error looked like this in the Actions log:

```
[WARN] Failed to call GitHub API: curl: (22) The requested URL returned error: 403
[WARN] Failed to create GitHub issue comment
[WARN] Error while posting pull request summary
```

Lint failures are still correctly reported — only the inline PR comment
was missing.

## Technical Details

- Added `pull-requests: write` to the `permissions:` block in
`.github/workflows/Lint-Repository.yml`.
- When a reusable workflow defines its own `permissions:` block, it
overrides (not inherits) the calling workflow's permissions. The parent
workflows (`workflow.yml` and consumer repos) already grant
`pull-requests: write`, but `Lint-Repository.yml` was restricting the
`GITHUB_TOKEN` to a narrower scope.
- No other workflows or jobs are affected — the permission is scoped to
the lint job only.
