Tim Oliver f8a339ce16 Updated and reintegrated Danger into GitHub Actions CI
Summary:
Danger is the build tool we've been using to proof-check incoming PRs, including making sure the incoming change is properly documented, and if needed, running SwiftLint on incoming Swift code.

Danger was originally running in our Travis CI implementation, but it wasn't integrated when we switched to GitHub Actions.

This diff updates our Danger dependencies to the latest versions, and integrates Danger into our CI system as a separate build step. I've also modified its SwiftLint setup so it will now lint Swift files in both our sample apps, and the Swift source files in `IGListSwiftKit` itself.
