[AUTO-CHERRYPICK] patch CVE-2022-21698 in keda - branch main (#7571)

Fixes CVE-2022-21698 for keda. The vulnerability is in the client_golang go module v1.11.1, and keda has a direct dependency on v1.11.0. Fixed by applying a patch to the keda code to update that module, then built the vendored tarball.
