Suggestion: Move assets from apps folder to libs/shared

[nikosanif]

Awesome work!

I have a suggestion regarding the structure since you use Nx Workspace.
You could move the entire apps/angular-spotify/src/assets folder to a more generic library (e.g. libs/shared/assets).
Thus, you can use pathing to any folder within the project (apps & libs) and will have nicely architectured new lib only for assets.

P.S. I can help on this issue if you want.

@nikosanif Cheers! I think having a shared lib asset is a truly a best practice. Feel free to refactor the code and create a new PR. I'll be happy to review it.

Notes: I am using lots of images for the repo README, please help to update there as well :)
