Update RXJS peer depenency version to include ^7.4.0

* Include versions ^7.4.0 into the allowed versions. They are allowed by Angular from 12.2.0 upwards
* Increase the lower bound of the RXJS 6.x dependency to ^6.5.3 to match Angular's actual requirements
  * Even @angular/core 12.0.0 already requires ^6.5.3

Fixes #2014
