fix(vulnerabilities): fix CJS interop for ae-cvss-calculator import

[Churro]

Changes

#40756 added a type cast to destructure fromVector that didn't work because ae-cvss-calculator is a CJS module. It led to _aeCvss.fromVector being undefined, causing TypeError: fromVector is not a function.

The fix ensures that the function is searched where it actually lives.

cast to any is also a bad idea, we totally loose type safety.
