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.

This CL doesn’t look good? This is what you can do:
* Revert this CL, by replying "REVERT: <provide reason>"
* File a bug under go/protobuf-transformer-issue for category ProtobufTransformer if there's an issue with the CL content.
* File a bug under go/rosie-bug if there's an issue with how the CL was managed.
* For all other issues such as the formatting of the CL, please file a bug under
go/clrobot-bug.
* Revert this CL and not get a CL that cleans up these paths in the future by
replying "BLOCKLIST: <provide reason>". This is not reversible! We recommend to
opt out the respective paths in your CL Robot configuration instead:
go/clrobot-opt-out.
