ci: skip Claude code review for Dependabot PRs

Dependabot PRs fail the claude-review check because the action rejects
non-human actors that aren't in the allowed_bots list. Since Dependabot
PRs are automated dependency bumps, they don't need a Claude code review.

Skip the job entirely when the actor is dependabot[bot].
