[Feature Request] Add to scalapb common protos

[sacsar]

Feature description:

Update https://github.com/scalapb/common-protos to include the protovalidate protos, not (only) the protoc-gen-validate protos.

Problem it solves or use case:

In order to use scalapb-generated code, one needs a scalapb-generated class for all the dependent protos. Depending on protovalidate-java as the source of protos won't work, even if one can use the library for validation.

Proposed implementation or solution:

Add protovalidate-java as a dependency in scalapb/common-protos.

Contribution:

I might just do it myself, but I don't know when I'll get to it. I'm currently working around it by vendoring the protos and just generating code for them directly.

Examples or references:

The pgv protos are added to scalapb/common-protos in https://github.com/scalapb/common-protos/blob/e4e0254817d801a009d63b1e51be81b0f1f00b63/build.sbt#L32

@sacsar I ran into an issue when the protobuf with "import "buf/validate/validate.proto" compile by scalapb

Import "buf/validate/validate.proto" was not found or had errors.

Could you share how you fix it?

I'm just generating code with scalapb for the protovalidate protos alongside my protos that reference them.

Do you mean to download "buf/validate/validate.proto" to local and then run scalapb?
Could you share the build.sbt about protos compile?
