Fixed Typo (Boostrap -> Bootstrap) / German translation

[zoh48gz04]

Farsi and Urdu might have to be changed?

Hi
looks good!
Just missed the switch for german language into:

../src/app/shared/components/header/header.component.html around line 72
<a class="dropdown-item" href="javascript:void(0)" (click)="changeLang('de')">{{ 'German' | translate }}

and into ../src/app/app.component.ts line 10 and 13
translate.addLangs(['en', 'fr', 'ur', 'es', 'it', 'de', 'fa']);
translate.use(browserLang.match(/en|fr|ur|es|it|de|fa/) ? browserLang : 'en');

Also for each language the key/value (json) translation for 'German' is missed...

Had the changes on disk but not commited..
Sorry for the commit mess, my dev environment of this project's embedded in another one.
Tell me if you want a clean up.

I don't have write access to this git repo.
I only can tell that your changes looks good for that desired functionality.
