Migrate to Swift 5️⃣.5️⃣ (#250)

GH Actions' macOS 11 images have Xcode 13 available which means that
Swift 5.5 is available to use in CI.

https://github.com/actions/virtual-environments/blob/main/images/macos/macos-11-Readme.md#xcode

## Changes

- Update `ci.yml`:
  + `DEVELOPER_DIR` to point to Xcode 13.2.1.
  + `IOS_SDK` to point to `iphonesimulator15.2`.
  + `PLATFORM_TARGET` to point to `x86_64-apple-ios15.2-simulator`.

- Update Package.swift's `// swift-tools-version` to 5.5.

- Update podspec's `swift_version` to 5.5.

- Set Swift 5 version at the project level.

- Update `carthage.sh` workaround for Carthage/Carthage#3019 to handle
Xcode 13.

- Update `README.md`.
