No golang in dev environment/shell

[Wesley]

Describe the bug
Starting a shell does not provide any go binary.

To Reproduce
Follow the steps in: https://github.com/tweag/gomod2nix/blob/master/docs/getting-started.md

mkdir test && cd test
nix flake init -t github:tweag/gomod2nix#app
nix develop
# Wait for shell
which go

Returns: which: no go in (...)

Expected behavior
I would expect mkGoEnv to give me the golang binary with the correct version from my go.mod file.

Environment

• Linux
• Version of the code: master
