docs: regenerate plugin readmes

Expose the serverUrl parameter for EU data residency support and
trackAutomaticEvents for Android. This requires the corresponding
cordova-plugin-mixpanel update (samzilverberg/cordova-mixpanel-plugin).

Usage: this.mixpanel.init(token, true, 'https://api-eu.mixpanel.com')
