Detail generating code in the Readme

[elliotmjackson]

#48 highlights there may be some documentation gap in generating code, I propose a detailed generating code section to combat this

[Alfus]

doesn't this need an option to generate included protos too?

[Alfus]

actually it looks like you need https://buf.build/docs/reference/cli/buf/generate/#include-imports

[Alfus]

looks like you either need to use https://buf.build/docs/reference/cli/buf/generate/#include-imports or manually generate the files using https://github.com/bufbuild/protovalidate-python/blob/main/Makefile#L39

This feels a longer-winded than necessary. I definitely wouldn't suggest people experiment with both buf and protoc 😛

Instead of a whole section about this, just make it clear above that to use the runtime library after pip install, they also need to generate the Python code for the core buf.protovalidate Protobuf package, and provide examples using buf. (I would leave protoc as an exercise for the reader: after all, very few people using protoc use it directly but usually have their own tooling around it or maybe use bazel.)

With buf, you can suggest that using --include-imports flag will probably do what they need or suggest they separately run buf generate buf.build/bufbuild/protovalidate.

Better. Ship it!!
