FFI elixir interop: document how to get stdlib by adding an empty elixir module

[inoas]

... or add a feature to gleam.toml maybe to explicitly load elixir stdlb by creating an empty elixir module via gleam tooling?

Thank you. I'm not totally sure where we would document this. Need to give it a think.

It would be nice to have a proper way to solve this problem too. Maybe some flag in gleam.toml to force using Elixir.
