Angular animations lacks the browser support (especially FireFox)

[lunayach]

Description

As a developer,
I need to ensure that my application runs well in most of the available browsers,
so that I can improve User Experience in general.

Mocks

Angular Animations API is built on top of the Web Animations API and this shows that only 75.65% of the web browser traffic supports this API.

Acceptance Criteria

Update [Required]

• We need to add a Polyfill (i.e. provide the browser with the technology, that it lacks it natively). In this case, in polyfills.ts, we need to uncomment the line, //import 'web-animations-js' and Run npm install --save web-animations-js

Enhancement to Update [Optional]

• We may mention the minimum Version support in all major browsers for our application in Readme.md.

Definition of Done

• All of the required items are completed.
• Approval by 1 mentor.

Sounds good @lunayach . Just make sure it doesn't impact anything else.
