configure: error: cannot import Python module "distutils".
Please check your Python installation. The error was:

I also ran into an error when building in a nix shell under NixOS 24.05:

python3 -m grpc_tools.protoc -I cln-grpc/proto cln-grpc/proto/node.proto --python_out=contrib/pyln-grpc-proto/pyln/grpc/ --grpc_python_out=contrib/pyln-grpc-proto/pyln/grpc/ --experimental_allow_proto3_optional

I tried around with installing a lot of different nix and python packages, but wasn't able to get rid of this error. The closest I've come was to add the missing python package mako and remove duplicates in the nix-shell command:

diff --git a/doc/getting-started/getting-started/installation.md b/doc/getting-started/getting-started/installation.md

 Use nix-shell launch a shell with a full Core Lightning dev environment:
 
 ```shell

My guess is that I need to manually add a library to python in the shell along the lines of this post, but that's where my nix abilities end.

Still need to look into it, but thanks for this diff will be really helpful
