Bump @types/puppeteer from 2.1.4 to 2.1.5

Editor assessment

The subject names the types/puppeteer bump with both versions and the pull request number, so the update is unambiguous, and the build type with the deps-dev scope is the correct classification. There is no body, appropriate for a routine dev dependency and free of changelog boilerplate. The header is imperative and unterminated. Immediately clear and accurately typed; the only shortfall is the absent rationale, which is acceptable for a version bump.
