Some updates to handle different cases for e2e run

[bobzilladev]

What

Changes that made the e2e tests work for me, these may not be universally applicable, so happy to cherry pick anything that is actually useful.

How

• Typo in developer guide
• Kustomization changes in e2e-fixtures/hello-world-ingress to remove bezek-hello-world-ingress-2 and set via config
• e2e-fixtures/ingress-class 404 is HTTP/2 for me
• The secrets keys don't seem to have NGROK prefix, unlike the environment variables they set
• jq and yq weren't installed on this machine, added to nix config, and added some bash to check for them up front. looks like josh is adding nix support though, so this may become irrelevant.
• Changed the test for GOOGLE_CLIENT_ID to not error out if not defined, due to the set -eu -o pipefail
• A message before the long sleep to make the lack of output more expected

So i was the only one using these for the most part and near the end of the sprints things changed heavily and these got out of date. They still have the old annoation system we had before we used crds https://github.com/ngrok/kubernetes-ingress-controller/blob/main/e2e-fixtures/route-modules/route-modules.yaml#L6-L11

We may want to chat with you and the team about if you find these useful or if there are some changes we can make to make things a bit better. I think these tests end up having various state problems and actually were hitting api rate limits quite frequently
