Update syft image and doc - use docker commands

[pauld-msft]

Syft image update to newest version.

Updated docs as well since Skopeo has issue with authenticating with ACR. Also, it requires WSL to be setup as there is no Windows support.
Docker tagging and push works for this scenario, so we can use that instead: containers/skopeo#1534

👋 Hi! It looks like you modified some files in the Detectors folder.
You may need to bump the detector versions if any of the following scenarios apply:

• The detector detects more or fewer components than before
• The detector generates different parent/child graph relationships than before
• The detector generates different devDependencies values than before

If none of the above scenarios apply, feel free to ignore this comment 🙂

Let's bump the linux detector version to reflect an underlying change in the detector
