feat: support Angular 20 (#1220)

Adds Angular 20 support.

This also remove the custom jest setup as it was not compatible with
Angular 20 and uses builtin support for vitest in Angular 20.
For this, Angular has been removed from the jest setup and the pipeline
runs it separately now.

Fixes #1206
