[Documentation]: Update Stackblitz example to Signal Queries

[geromegrignon]

Hi, I just discovered your project through LinkedIn!

By landing on the documentation, I noticed the Stackblitz embedded project is still using @ViewChilddirectives.

You might want to update it to viewchild() Signal Query:

  consentTemplateRef: TemplateRef<any> = viewChild.required<TemplateRef<any>>('consentTemplate')

  submitTemplateRef: TemplateRef<any> = viewChild.required<TemplateRef<any>>('submitTemplate');
