Update workbox plugin to 5.1.2 resolving ServiceWorker quota exceeded errors

[jflayhart]

Currently our e-commerce site is experiencing millions of ServiceWorker DOMException: QuotaExceededError errors, which is blowing through our monthly Rollbar limit 😬. I did some brief research and found that Google is aware of this issue and recommends purgeOnQuotaError to potentially fix most of these runtime quota issues.

I could be mistaken, but looks as if CRA is using workbox 4.3.1, and this purgeOnQuotaError was added in 5.1.2 as default enabled.

Being that we at Shipt use CRA, since it follows best practice standards, I highly suggest we update Workbox plugin ASAP so we can be on par with Google's best practices for handling ServiceWorkers.

I would love to do the PR myself, but wanted to post here for thoughts or concerns. Although, I would be surprised if anyone is opposed to not following Google's recommendations by updating workbox 👍

Thanks and love this app!
