[programmer04]

Problem Statement

Since KO 2.2.x has been released, the chart released for this version should be used to upgrade from.

TestHelmUpgrade in test/e2e/helm_install_upgrade_test.go shouldn't require

• stepsToDoBeforeUpgrade (see log line "Applying Gateway API CRDs for v1.5.1 due to PR #3491") - manual upgrade of GWAPI CRDs
• restart of DataPlane's ``Deploymentis not expected (see"Applying Gateway API CRDs for v1.5.1 due to PR chore(deps): bump sigs.k8s.io/gateway-api from 1.4.1 to 1.5.0 and make required adjustments #3491"`) - it should assert that it's non-patched

Proposed Solution

Update that test to get rid of specific adjustments for upgrading to KO 2.2.x

Acceptance Criteria

• TestHelmUpgrade is adjusted according to the description
