Pete Bacon Darwin 7bcfc0db09 refactor(core): remove isObservable TODO (#39669)
This commit removes the TODO comment that proposed
that we use the built-in RxJS `isObservable()` function.

This is not a viable approach since the built-in function
requires that the `obj` contains additional methods that
our "observable" types (such as `EventEmitter`) do not
necessarily have.

See #39643 for more information.
