Package.swift: fix deprecated dependency initializers (#748)

* Package.swift: fix deprecated dependency initializers

* Fix remaining uses of deprecated initializer

* Package.swift: keep `name:` initializer to match `swiftpm` to `swift-package-manager`

This checkout path is hardcoded in `update-checkout-config.json` of our `swift` repository and can't be easily changed, so we have to keep this initializer call.
