Subject: [PATCH] [SK2] Add `Configuration.with(storeKitVersion:)` to select
 the version of StoreKit to use (#3487)

This PR introduces a new configuration option to select the StoreKit
version to use.

It supersedes the deprecated `.with(usesStoreKit2IfAvailable: true)` and
the internal `usesStoreKit2JWS` configuration options.

Uses JWS tokens instead of SK1 receipts when in StoreKit 2 mode where
applicable.

Example usage:
```swift
Purchases.configure(
            with: .builder(withAPIKey: apiKey)
                .with(storeKitVersion: .storeKit2)
                .build()
```
