Support for Angular v20

[felixgeissler]

I tried to upgrade one of my projects utilizing your handy package to Angular v20 and encountered this Yarn Post-resolution validation issues:

...
➤ YN0060: │ @angular/common is listed by your project with version 20.0.0 (p8a433), which doesn't satisfy what angular-tabler-icons and other dependencies request (but they have non-overlapping ranges!).
➤ YN0060: │ @angular/core is listed by your project with version 20.0.0 (p2948a), which doesn't satisfy what angular-tabler-icons and other dependencies request (but they have non-overlapping ranges!).
...

This PR should add Angular v20 support. I also updated the sample app to validate that v20 indeed works as expected.

Yes, please update the package dependencies

@pierreavn Hope to review as soon as possible. Additionally, it is recommended to find two more people as collaborators and grant them writing permissions. Because I noticed that the author is quite busy and doesn't seem to have time to maintain and follow up on the project in a timely manner.
