Add Unpacked Items to Packs

[ben-githubs]

Background

After revamping the check-packs function in PAT, we discovered a number of rules that weren't assigned to any Packs. This PR either assigns them to a pack, or adds an exception tag to exclude them from the check.

Changes

• Added a new pack for GCP K8s
• Added exceptions for the Crowdstrike Unmanaged Device rules
• A bunch of other rules got added or excluded from packs

Testing

• pat check-packs passed, so there shouldn't be any issues with missing pack dependencies
• pat validate passed
• All of these rules have already existed in the repo, so if they have noise issues/bugs, we should know about them by now. They should be fine to add to packs.

Should we create a GitLab pack?

There's only 2 detections, which is why I didn't bother. I know that means that Console-only folks won't get this detection, but I personally feel rather than release a tiny pack, it's better to just wait till we use pypanther to manage content delivery. Lmk if you feel differently!
