Run Browserker active checks in DAST

Problem

The DAST team have spent time building custom active checks. Currently, these are not running on a browser-based DAST scan.

Proposal

Document and run custom active checks.

Implementation plan

• Document the 22.1 active check in the DAST documentation.
  • This can either be done manually, or generated with the passive check documentation. Any solution should be tailed toward getting it done quickly (MVP). (done in another issue/MR)
• Enable the 22.1 check in DAST/ZAP for a browser-based full scan (make other browserker active checks will not run)
• Disable the 6 ZAP check in DAST/ZAP for a browser-based full scan.
• Ensure that all other ZAP active checks run for a browser-based full scan.
• Note: only release an MR turning it on when feature is tested and other engineers/product team agrees.
