update(dockerfile): revert KICS user change from 65532 back to root

[cx-ruiaraujo]

Reason for Proposed Changes

• KICS always used root, but in the latest release, we changed it to 65532 due to FedRAMP policies. This change is causing issues in AST-CLI. Since we only use the binaries inside the image, there is no relevant reason to use 65532 instead of root. A possible fix is to run the KICS image with the same user as the container running it. However, since this would require users to change their setup, I am reverting this change to avoid that and to prevent other potential issues.

Proposed Changes

• revert KICS user change from 65532 back to root
• update KICS gh action to v2.1.4
• fix vulnerabilities

I would much rather prefer the solution you provided "A possible fix is to run the KICS image with the same user as the container running it" but I understand the problem with that.
LGTM eitherway.
