[gRPC] Cannot find a way to add dependencies to buf

Is your feature request related to a problem? Please describe.
I can't find a way to tell the kotlinx-rpc plugin about BSR deps for example buf.build/googleapis/googleapis

Describe the solution you'd like

Something shaped like this seems natural but doesn't exist:

rpc {
    protoc {
        buf {
            generate {
                includeImports = true
                includeWkt = true
            }
            // no place to declare `buf.build/googleapis/googleapis`
        }
    }
 }

Describe alternatives you've considered
Two workarounds I've actually used while migrating from Wire:

1. Patch the generated buf.yaml in a doFirst hook.
2. Copy the BSR protos into src/<sourceSet>/proto/.

Hey @honzamalousek! Thanks for the request!
I'm now working on supporting configurations: #679
I wonder it this would fit the same case. But is not, I'll add a separate support for BSR

Thanks @Mr3zee for looking into this!
For my specific use case (googleapis) #679 would probably work - there's a Maven artifact com.google.api.grpc:proto-google-common-protos that ships the same .proto files, but i still think that adding support for BSR would be beneficial, for cases like company's private BSR module, or any BSR-only schema with no Maven mirror.
