test: reduce flakes on pages-dev e2e tests (#10280)

Occasionally this test flaked because the dev process output the bindings twice.
I believe this is a timings issue around watching for file changes, triggering a second update and printing of the bindings

So now we only extract the first bindings list and clean it up to make it resilient to flaking
