Hello, I've created this PR for the Angular update: #157

[davide1995]

@epitzalis Thanks for it but the pipeline is red. Could you please check it?
@chihab In order to avoid waiting times with a next Angular release, should not the dependency be less strict about which Angular version is attached to?

Hi @davide1995 I can't fix that error because it's a pipeline error that requires a Node version change. I don't have permission to do that. I'm waiting to see if @chihab can change it
