Adopt Latest PHC Version

[fire-at-will]

This PR updates the KMP SDK to consume the latest changes in PHC 13.0.1. Once it is merged, we should be ready for a beta 3 release.

Description

Specifically, this PR:

• Bumps required OS versions and PHC version
  • iOS 13
  • PHC 13.0.1
• Introduces a new StoreKitVersion enum
• Changes the PurchasesAreCompletedBy enum to now be a sealed class, requiring a storeKitVersion to be provided when the value is set to MyApp
• Adds storeKitVersion to the PurchasesConfiguration object
• Adds the recordPurchase function to Purchases.
  • Changes StoreTransaction to be a class on iOS. For now, it remains a typealias on Android due to some conflicts in purchases-ui
• Introduces unit tests for the first time! 😄
• Runs the unit tests in CI for pull requests and on the main branch.
• Updates the apiTester and apiDump files

@tonidero About SubscriptionOption.installmentInfo - it looks like the Android SubscriptionInfo object is actually a typealias for the Android com.revenuecat.purchases.models.SubscriptionOption, which already has installmentInfo added to it 😄

@tonidero @fire-at-will Yea that's true, but this means it's only usable in the Android source set. I think it's beneficial if we can access it from the common source set, so for that we'd need to add a public API in commonMain/[...]/SubscriptionOption.kt. However, we can also do that when we converting away from typealiases (but we should make sure not to forget).

@JayShortway I'll give it a shot! Will be back in a few minutes! :D

@JayShortway @tonidero The changes to add InstallmentInfos started to be spread across several files, so I opened a PR into this branch to make it easier to review: https://github.com/RevenueCat/purchases-kmp/pull/150
