feat(android): Redirect to Google Play Store if WebView is below the minimum

[thomasvidas]

Fixes #4884

[thomasvidas]

Future improvements to be made:

• Customizable text/icon. Should we add this to the Capacitor config?
• Localization. We should check the locale and use the localized version of this message for non-English speaking countries.
• Better support for Android R and above. The R minimum WebView version is 61, but the TYPE_TOAST was deprecated in O, and the replacement requires a system permission. We should modify the splash screen plugin to allow this alert on top or add steps on how to add the permission.
• Allow users to specify their own minimum, allowing them to set their app to a minimum of WebView 80 should they wish to

I was investigating and the problem comes from chrome, which has a version lower than 60, so what I implemented was to force it to be updated, I created that script and put it in the angular index.html. It worked very well for me.
<script type="text/javascript"> var userAgentArray = window.navigator.userAgent.split(" "); var chromeVersion = a.find(c => c.includes('Chrome/')); var version = b.split("/")[1]; var numberVersion = parseInt(c.toString().split(".")[0]); if(numberVersion <=60) { alert("Debe actualizar su navegador chrome.") var url = "https://play.google.com/store/apps/details?id=com.android.chrome"; window.open(url); } </script>
