[WiP] naren/support arm e2e tests

[narphu]

This WiP PR allows us to run E2E tests for a Multiarch image (x86 and ARM). This is subject to setting up an ARM runner for the ARM section of the tests. The multi-arch image can be private one if triggered from Jenkins or the public image.

Following are a summary of changes to enable these E2E tests to be multiarch:

• Upgrade relevant images that are used by the E2E tests to support multiarch. Ex: bitnami/kubectl:1.20.4 to bitnami/kubectl:1.30.4, since 1.20 version was a x86 only image. amazon/aws-cli:2.2.24 and other cloud CLI images are upgraded as well.
• Use quay.io/helmpack/chart-testing image instead of kubectl image for tests that require to cURL. The new versions of Kubectl no longer come with stock cURL package installed, so I switched to rather use chart-testing image which we already use for other purposes and comes with cURL installed.
• Add an ARM runner in the Github workflow, so that tests run on both ARM and x86.
