Automated g4 rollback of changelist 618466227.
*** Reason for rollback ***
spend_token_data.proto update broke chromium build.
*** Original change description ***
Fix 15 ProtobufTransformer findings:
* Upgrade to the latest edition (15 times)
* See go/editions for more information about this migration.
* Based on blaze dependency analysis, these protos were found to only used in languages known to support editions.* If this proto is later required in a language that doesn't support editions yet, a pure rollback is safe and recommended.
See go/protobuf-edition-zero-lsc for more information on why you've received this change and why it is important.
