GCP Improvements Quicky

[jonrau1]

GCP was the second CSP I added support for, then quickly forgot about it because I suck at writing Python and GCP docs aren't great. Well now I'm many years wiser, and I still suck at Python, but I can read a bit better. Which is good because GPT o3-mini and whatever the hell GitHub CoPilot use absolutely make shit up when it comes to the lower-level googleapiclient.discovery.

Anyway...

• Fixed the GCP Assessment Target! I broke it when I did the TOML refactor a year or so ago, shows me that no one uses it lol. Fixed a bug where I had the wrong argument
• Uses a GCP Credentials object to pass to the various clients instead of writing to a file and passing the path to file as an ENV VAR. One day I need to swap to WIF support.
• Added 2 new auditors, a 2-check BigQuery auditor (that's all you can really do) and an IAM Auditor I will come back to (next year lol)
• Updated the docs to annotate how to properly escape an IAM SA JSON Key, if you choose to paste it into the TOML
• Updated iconography, control statements, and the big check tracker readmes
• Bumped to Alpine 3.21.3 as of 2 days ago (13 FEB 2025)
