fix: handle webview version names on custom ROMs

[colenso]

I noticed that some custom ROMs that have the string "Developer Build" in their info.versionName. Hence, adjusted the code to use a regex that finds the first sequence of digits instead.

To add some context, I made this fix because of an error that crashes some of our user's apps. This is the stacktrace that firebase crashlytics has provided us:
