George Kalpakas d9dc46e651 fix(service-worker): ignore invalid only-if-cached requests (#22883)
Under some circumstances (possibly related to opening Chrome DevTools),
requests are made with `cache: 'only-if-cached'` and `mode: 'no-cors'`.
These request will eventually fail, because `only-if-cached` is only
allowed to be used with `mode: 'same-origin'`.
This is likely a bug in Chrome DevTools.

This commit avoids errors related to such requests by not handling them.

Fixes #22362
