Keep iOS chrome identified as safari because it is

This section of code ends up causing issues in other areas because iOS Chrome is actually Safari (WKWebView technically). It does not support webm recording like usual Chrome, but instead natively supports mp4 recording like Safari. So you should not be making determinations of what is usually supported in Chrome if it is actually a WKWebView.

This causes the "auto" recorderType determination to end up trying to use WebAssemblyRecorder when it should use MediaStreamRecorder. Furthermore, if you force MediaStreamRecorder to be used, then it ends up failing the isMediaRecorderCompatible check (because it thinks it is in Chrome but that helper internally doesn't factor in CriOS) which overrides any recorderHints passed in.

It's better to just treat CriOS browsers as Safari, because again it is a WKWebView which should be just viewed as Safari.
