Make standalone import the default

[rajinder-yadav]

Since Angular now defaults to standalone component, it only make sense for ionic imports to be standalone by default.

It gets tedious to type something like:

import { Config } from '@ionic/angular/standalone';

vs

import { Config } from '@ionic/angular/';

Make NgModule based apps use:

import { Config } from '@ionic/angular/ngmodule';

If you wait too long to make this changes, when NgModule becomes deprecated, then you're going to force dev either to continue to use the long form import which is stupid, or force them to make the changes manually.

I say make the people upgrading take the hit and spare the rest of us.
