feat: improve project fetching by using single-project command

[tshedor]

Description

This changes project fetching to grab only the desired project instead of finding it in a whole list of available projects. It still confirms the validity of the project by ensuring the project has apps.

Fetching a full list of available projects isn't necessary and sometimes takes too much time when an account is connected to a large quantity.

Hey I don't know if I can legally accept the contribution agreement but this is such a small PR that I don't care about credit for the fix. If a core contributor wanted to open a PR with this exact code under their name, that'd be totally fine.
