cleanup: remove trailing spaces from project template

[brodycj]

Platforms affected

Android

Motivation and Context

see title

Description

• remove trailing spaces from bin/templates/project/AndroidManifest.xml
• remove trailing spaces from bin/templates/project/assets/www/css/index.css

open question: I was wondering if we should really keep www assets committed in cordova-android or any other repos? Shouldn't we just use the www assets from the app-hello-world template?

Testing

I believe these are required for the platform-centred workflow where users download cordova-android and then use the bin/create script to create new projects as opposed to using the cordova CLI.

Makes sense to me. I wonder if we should consider doing anything to keep these in sync, like we do with cordova.js.

I definitely recall discussions of removing platform-centered workflow. I would personally favor keeping it whenever possible, don't really like the added support burden though. I wonder if we could find some way to automate this.
