Request: update samples to use nothing that is deprecated

[AndroidDeveloperLB]

It seems a lot in the code is deprecated:

 billingClient.querySkuDetails(
                SkuDetailsParams.newBuilder()

billingClient.queryPurchasesAsync(BillingClient.SkuType.INAPP)

purchasesResult = billingClient.queryPurchasesAsync(BillingClient.SkuType.SUBS)

val purchasesResult = billingClient.queryPurchasesAsync(skuType)

and a lot more: https://github.com/android/play-billing-samples/blob/main/TrivialDriveKotlin/app/src/main/java/com/sample/android/trivialdrivesample/billing/BillingDataSource.kt#L358

Please update the samples to use the latest API. Don't leave anything that is deprecated.
