also include relevant motivation and context. Have in mind the following
questions:

Move the `prep_environment` flow to before `install_detox`. This fixes
the failed detox cli installation part in `detox-setup.sh`

## **Related issues**

Fixes: #11465

## **Manual testing steps**

- Run the `pr_smoke_e2e_pipeline`
- Check that `install_detox` workflow successfully installs detox cli
within the tests. Here's an example of a failing one
https://app.bitrise.io/build/fa9fa7b1-80bf-4233-8bda-96cdaafe5ff4
- Tests should run successfully
