Update build tools.

[pixlwave]

This PR makes 2 changes:

• Un-pin versions to update tools on each release.
  • SwiftLint isn't updated regularly, this will help us keep updated but in a more stable way than on EX as running pod install will still give reproducible results.
• Switch to SwiftFormat as a pod
  • Ensures that it is run for everyone and not skipped if it hasn't been installed.
