fix: fixing protoc compilation with sed

There is a protoc-gRPC compile bug with Python which I was solving manually after compiling the .proto file. Check the README for more details about the bug.

This MR solves the bug within the "compile_proto.sh" and "specific_compile_proto.sh" which are the compile process to generate the protoc Python files. So we don't need to do this more manually.

Why: not only because we have to do manually, but it is making the docker deployment harder.
