Profile screen accessibility snapshot

[DimitarNestorov]

• Added https://github.com/cashapp/AccessibilitySnapshot as a Swift Package Manager dependency
  • I generated the snapshot on Apple Silicon but GitHub Actions is still running Intel so there's a small difference (not visible to the human eye). Using this version from this comment: Add precision and tolerance apis cashapp/AccessibilitySnapshot#63 (comment)
  • Read more: Perceptual image precision + 90% speed improvement pointfreeco/swift-snapshot-testing#628
• Made a simple snapshot of the Profile component
• Added a GitHub Actions workflow to run the tests
  • Instead of running the packager while the tests are running I just added FORCE_BUNDLING=1 to ios/.xcode.env.local and a custom USE_LOCAL_BUNDLE
  • In case the tests fail all the non matching screenshots will be uploaded as artifacts so you can easily download and compare them
  • The workflow caches CocoaPods and derived data

Xcode failed when running tests.

Check the workflow logs and artifacts.

Forgot to check if the app actually builds. Turned out I was linking the app target to the testing frameworks. Fixed in c994a7d.

Turns out I didn't need to link SnapshotTesting. When adding AccessibilitySnapshot I just had to select the correct target.
Fixed in #6
