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
yarn cli build web --environment=production    # same as ^
yarn cli build web --clientId=foo                          # build web with clientId of 'foo' 
yarn cli build nodePckgs                                       # build node package

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
