nb: Use bashInteractive to fix shell subcommand (#375817)

The `nb shell` subcommand relies on Bash's `read` and the default Bash
in stdenv has unexpected behavior, characters aren't echoed and arrow
keys do not seem to recall history.

By adding `bashInteractive` to the buildInputs, patchShebangs picks it
up and this fixes the behavior.

Fixes #374606
