Removed BillingFlowParams.ProrationMode, BillingFlowParams.SubscriptionUpdateParams.Builder.setReplaceProrationMode(), and BillingFlowParams.SubscriptionUpdateParams.Builder.setReplaceSkusProrationMode().
Developers should use BillingFlowParams.SubscriptionUpdateParams.ReplacementMode with BillingFlowParams.SubscriptionUpdateParams.Builder#setSubscriptionReplacementMode(int) instead.
BillingFlowParams.SubscriptionUpdateParams.Builder.setReplaceProrationMode().
BillingFlowParams.SubscriptionUpdateParams.Builder.setReplaceSkusProrationMode().

This seems like another one that maybe dependabot shouldn't manage, and instead it should be bumped manually when new features are needed? @gmackall wdyt?

This is going to be covered by #8218

I think that is reasonable, though we have in the past been able to land a couple small dependabot upgrades iirc. But it is not very common

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
