Silent errors for offline PWA

[Tymek]

Describe the feature request

I am trying to get rid of the console error Unleash: unable to fetch feature toggles TypeError: Failed to fetch when our PWA is offline. We are using the React Client, is there a way to remove the errors while offline?

Background

https://unleash-community.slack.com/archives/C03GWTN7XMG/p1702460982222809

Solution suggestions

I think we could introduce "silent" mode or log verbosity. Here is the line responsible for console errors, but console.error is in use also in other places:

unleash-proxy-client-js/src/index.ts

Line 455 in 4a4056d

console.error('Unleash: unable to fetch feature toggles', e);

A log verbosity would be nice 😄
