I am using renovate bot to update go dependencies in my repo. I want to run some postUpgrade commands which require protobuf-compiler and the only way to install this is to run the renovate as a root user in docker and then install the required packages. Is there any possibility to add protobuf-compiler in the renovate base image. I gone through the following discussion:
#23500
