Remove Protractor test from CI examples

Editor assessment

The subject states the removal — Protractor tests deleted from the CI examples — and the body supplies the reason: new projects have not included Protractor since Angular version 12, so the examples no longer reflect reality. That is a complete rationale for a documentation cleanup. Type `docs` is accurate; absent scope is tolerable for a named example area. Footers are well formed: `PR Close #41733` trailer, with the capitalized `Remove` being a permitted stylistic choice. Style is otherwise clean — no trailing period, moderate length, no junk. A clear, motivated, publishable example of keeping documentation examples current, with only its brevity limiting depth.
