Create Inboundfilter for: @webkit-masked-url: (//hidden/)

[HazAT]

See title, let's consider adding a default inboundfilter in Sentry to filter out these unhelpful/unactionable errors.

Discussed in #5875

Hello. I began to see such errors in my project:

//hidden/ in y@webkit-masked-url: at line 2:2930760
//hidden/ in fromAny@webkit-masked-url: at line 2:2931890
//hidden/ in _handleResponsePromise@webkit-masked-url: at line 2:1144366
//hidden/ in _handleDispatchResponse@webkit-masked-url: at line 2:1144141
//hidden/ in _handleMessage@webkit-masked-url: at line 2:1143837
//hidden/ in @webkit-masked-url: at line 2:1143638
//hidden/ in emit@webkit-masked-url: at line 2339:17
//hidden/ in @webkit-masked-url: at line 2138:26

I can't understand what it is, why the sentry throws them. It looks like a code problem in Safari itself

So after checking in again with @lforst , I think what we want to do here is not add a new config/rule, but add this to the filters:browser-extensions rule we already have. Which means nothing really to do on our end, just change stuff in relay. I'll check with relay folks!
