It's both unexpected and undesirable for `brew bundle (exec|env|sh)` to filter the environment and makes these tools less useful. Not filtering the environment, though, causes issues with the `brew bundle sh` shell. Fix this up and, while we're here, also improve the formatting for both `zsh` and `bash` (the default) to use nicer and more consistent prompts and colours. To simplify this, consolidate some logic in a new `Utils::Shell.shell_with_prompt` method and add tests for it and a similar notice for `brew bundle sh`. Finally, avoid printing out the notice when `HOMEBREW_NO_ENV_HINTS` is set.
