Add setup script for internal-encryption e2e test

[KauzClay]

Proposed Changes

• test does nothing now, will be implemented in a later PR (Implement e2e test for internal encryption #13536)
• First in a series of PRs to add an e2e test for Internal Encryption feature. Doing things this way so I can get the infra in place first to make development easier and not block others.
• In support of implementing internal encryption for net-contour here: net-contour supports internal encryption configuration knative-extensions/net-contour#819.

the kourier-tls e2e tests seem to be failing when they source test/e2e-common.sh. It breaks in this block: https://github.com/knative/serving/blob/main/test/e2e-common.sh#L64-L77

Based on what I see here (https://github.com/knative/serving/actions/runs/3716649646/jobs/6303260544#step:10:249), LATEST_SERVING_RELEASE_VERSION isn't set.

Idk where to find "latest_version" or how to find out what it is supposed to be there: https://github.com/knative/serving/blob/main/test/e2e-common.sh#L74

I believe the failures I'm seeing are related to #13566 (comment)

I don't think this is related to the change I'm trying to make, so do you think I can get the okay to have this merged? @kvmware

[psschwei]

I retried the failing jobs... since they seem to be flakes, hopefully they'll pass this time (probably best not to override the tests if we don't have to)

Hey @psschwei , it looks like the tests passed. Do you feel comfortable giving it the okay?

(the HPA test in the istio prow job is running into some GKE issues, so 🤞 )
