Typescript 5.6.x compatibility with ObservableSet and Observable Map

[ymor]

Intended outcome:
ObservableMap should implement Map correctly and ObservableSet should implement Set correctly

Actual outcome:

Type 'ObservableMap<unknown, unknown>' is not assignable to type 'Map<unknown, unknown>'.
  The types returned by 'entries()' are incompatible between these types.
    Type 'IterableIterator<IMapEntry<unknown, unknown>>' is missing the following properties from type 'MapIterator<[unknown, unknown]>': map, filter, take, drop, and 9 more.
Type 'ObservableSet<unknown>' is not assignable to type 'Set<unknown>'.
  The types returned by 'entries()' are incompatible between these types.
    Type 'IterableIterator<[unknown, unknown]>' is missing the following properties from type 'SetIterator<[unknown, unknown]>': map, filter, take, drop, and 9 more.

No errors in Typescript 5.5.x

Just ran into this issue too. I think we need to update ObservableMap to match the new structure for .entries() with the new iterator helpers.
