Feature Request: Add Support for Angular 17+

[HasibGit]

Hi,

Thank you for maintaining the ng2-dragula package — it has been a valuable tool for implementing drag-and-drop functionality in Angular applications.

I’d like to request an update to add support for the latest Angular versions (17, 18, 19, and 20). Currently, the package officially supports up to Angular 16, which limits compatibility for projects that are adopting newer versions of Angular.

As ng2-dragula continues to serve use cases where migrating to @angular/cdk/drag-drop is not feasible due to architectural constraints, updating support for recent Angular versions would greatly help teams relying on it.

Looking forward to your consideration. Thank you!
