ci(claude-review): allow dependabot PRs in Claude Code Review

The claude-code-action rejects bot actors by default, failing the
claude-review check on every Dependabot PR with:

  Workflow initiated by non-human actor: dependabot (type: Bot).
  Add bot to allowed_bots list or use '*' to allow all bots.

Add allowed_bots: "dependabot[bot]" so dependency PRs get reviewed
instead of showing a spurious red check.
