fix(plugin-js-packages): parse yarn 4 audit output correctly

[matejchalk]

Fixes bug reported by customer trying to integrate packages audit in Yarn v4.

Found out that in Yarn version 4, the output format of yarn npm audit --json changed completely compared to versions 2 and 3. Adjusted the stdout parsing logic to support both formats. Tested in rx-angular workspace.
