Closes #1505

Description

This PR updates the required E2E aggregate workflow to include missing jobs in the needs lists.

Specifically, it adds:

• argo-vpol
• karpenter-mpol
• other-ivpol

to the appropriate e2e-required-success and e2e-required-failure aggregate jobs so failures in these jobs are reflected by the required aggregate workflow status.

Checklist

• I have read the policy contribution guidelines.
• [] I have added test manifests and resources covering both positive and negative tests that prove this policy works as intended.
• [] I have added the artifacthub-pkg.yml file and have verified it is complete and correct.

@aerosouund PTAL
The failing E2E jobs appear unrelated to this PR. This change only updates the aggregate workflow needs list. The failed jobs are existing policy test failures, and the e2e-required check is failing because it now reflects those underlying failures as intended.
