fix(network_info_plus): Get SSID on Android 12 and newer

[vbuberen]

Description

As it turned out in Android 12 and newer SSID and BSSID are considered a location sensitive info, thus the new API to get WifiInfo via getNetworkCapabilities() returned all info except these 2 values. And it doesn't matter that app has required permissions. Explanation is provided in the official docs:
https://developer.android.com/reference/android/net/ConnectivityManager#getNetworkCapabilities(android.net.Network)

The suggested way to register a callback with required flag seems not the best option for the network_info_plus as we want to get info on demand, not wait till something changes in network configuration.

It seems we are not the only ones, who issue this problem: https://stackoverflow.com/questions/71281724/getting-wifi-ssid-from-connectivitymanager-networkcapabilities-synchronously

Based on the info above I decided to revert one of changes I made in #1151 and rely on deprecated function to get needed required info. I think we are safe to live till time comes to kill this deprecated API in next Android releases. However, hope that Google introduces some better API to not have only callbacks way.

Give user positioning permissions why you can't get SSID?
SSID = NULL
BSSID = 02:00:00:00:00:00
Positioning permissions I requested according to the Permission_handler plug -in.
Access_network_State does this require the user's consent?

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Future<void> setNetwork() async {
final info = NetworkInfo();
var locationStatus = await Permission.location.status;
if (locationStatus.isDenied) {
  await Permission.locationWhenInUse.request();
}
if (await Permission.location.isRestricted) {
  openAppSettings();
}

if (await Permission.location.isGranted) {
  var wifiName = await info.getWifiName();
  log('wifiName $wifiName');
  }
}
