feat: add Rokt Shoppable Ads support

[thomson-t]

Background

The Android Rokt SDK now exposes Shoppable Ads APIs for optional payment extension registration and shoppable placement selection. The mParticle Android Rokt kit needs matching public APIs so apps can register their payment extension through mParticle while keeping the existing identity and attribute enrichment behavior.

What Has Changed

• Added public Rokt kit facade APIs for payment extension registration and Shoppable Ads selection.
• Routed Shoppable Ads selection through the existing identity confirmation, placement attribute mapping, sandbox, MPID, and identity enrichment path before calling the Rokt SDK.
• Read stripePublishableKey from Rokt kit settings and pass it to the Rokt SDK as payment extension config during registration.
• Logged a selectShoppableAds mParticle event with finalized attributes.
• Updated the Rokt SDK dependency to 6.0.1-rc.2 for the local Shoppable Ads API build without adding the payment extension transitively.
• Added facade and Rokt kit unit coverage, README examples, and a changelog entry.

PR Summary

Medium Risk
Forwards dashboard Stripe publishable keys into the Rokt payment path and adds commerce-oriented SDK calls; scope is limited to the Rokt kit with tests and docs.

Overview
Adds Rokt Shoppable Ads support on the public Rokt facade: registerPaymentExtension and selectShoppableAds, wired through RoktKitRequestHelper with the same email/identity confirmation and attribute preparation used for selectPlacements.

registerPaymentExtension reads stripePublishableKey from kit settings and passes it to the Rokt SDK as stripeKey in payment config. Shoppable selection enriches attributes, logs a selectShoppableAds mParticle event (shared logRoktEvent helper), and calls Rokt.selectShoppableAds. The Rokt SDK dependency is bumped to 6.0.1-rc.2; README and changelog document optional payment-extension setup.
