Cli's build command always prompts for package

[tyler-dane]

Where did this happen?

Local code with an up-to-date main branch

Expected Behavior

When running yarn cli build web, I shouldn't be prompted for which package to build. Instead, the CLI will automaticlaly build the web package.

All of these commands work as expected:

yarn cli build web -e staging              # build web for staging env
yarn cli build web -e production        # build web for production env

Current Behavior

The CLI still prompts for the package to build

Steps to Reproduce

Run yarn cli build web or any combination of yarn cli build web [options].

Possible Solution

Fix the arg parsing so that the package is successfully interpreted before continuing the script

Context

This makes it more difficult for users to use the CLI
