Regenerate protos after swift-protobuf update to 1.28.0 (#2035)

`swift-protobuf` [released
1.28.0](https://github.com/apple/swift-protobuf/releases/tag/1.28.0)
yesterday, and it changed the headers in the generated files to disable
`swiftlint` (see apple/swift-protobuf#1627).
This means that our CI is now failing the sanity step when it checks the
generated files match the expected output of the `generate.sh` script.

This PR regenerates the protos with swift-protobuf 1.28.0 to include the
updated headers.
