ci(docs-infra): increase wait for SW on all origins to avoid CI flakes (#29988) 

In #29953, the wait period for SW on localhost was increased to avoid CI
flakes for the PWA score tests.

This commit expands the fix to non-localhost origins to avoid flakes in
the `aio_monitoring` job, when CircleCI VMs/network are slow.
(For reference, example failures: [289127], [289238])
