[Feature]: Remove karma/jasmine from generated app/lib if jest is selected as test framework

[mrednic-1A]

Context

Today a question is asked to select the testing framework when an application/library is generated. If jest is selected, the message to 'remove jasmine by hand is displayed'.

Proposal

Remove jasmine/karma deps and replace the test config in angular.json (for the app/lib generated) with the angular jest builder.
