Use of NotAction in an Allow statement

What this check finds

Using NotAction in an Allow policy almost always results in unwanted actions being allowed and should be avoided.

Passing looks like: No NotAction in Allow statements.

How to fix it

Rewrite the policy to use an explicit Action list instead of NotAction in Allow statements. This ensures only the intended permissions are granted.
