fix: Changing ubuntu image for CI pipeline to match the image used in…

… github PR workflow (#7318)

CI pipeline is failing frequently with transient timeout issues in e2e
testing. GitHub PR workflow does not fail for the same step. So updating
Linux image to ubuntu 20.04 in CI to match image version in GitHub PR
workflow.
