Migrate developer script to list-apps-in-pkg cmd

[danielbayley]

Part of #174192.

• list_apps_in_pkg

Script refactored, and now more reliably finds app sources from the pkg archive.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online <cask> is error-free.
• brew style --fix <cask> reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new <cask> worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask> worked successfully.
• brew uninstall --cask <cask> worked successfully.

Thanks for opening these command migrations @danielbayley

Because there are so many PRs that you have opened at once, I'm asking this question here but it does relate to a few of the open PRs..

For maintainability, have you considered combining the list-*-in-pkg commands into a single command with variables? I guess there are pros and cons, but I had mentioned it in the issue that you referenced.

I think it could also be worth discussing whether some of these commands should/could move into Ruby commands, because then we have better style, typing and linting checks available.

Possibly, what kind of API do you envisage for that? @bevanjkay

Refactored many of them, most are ready for review…
