Add Mirroring Guide for e2e.test / Conformance tests

[BenTheElder]

I think this will be a common use-case: Not needing to mirror core Kubernetes but needing to mirror the necessary components to use e2e.test

We should have a new docs/mirroring/e2e-tests.md with sections for "Identifying Images To Mirror" and "Using Mirrored Images". For the format see #213 as an example. We should additionally list this guide as "e2e tests / conformance tests: [...]" in the docs so people searching for conformance tests can find it.

• test/utils/image: Support a single repository kubernetes#93510
