refactor: 💡 Implement IObservable for Observable

[MightyM17]

Also use onUpdate naming instead of onUpdated to be inline with the interface.

Checks:

• Observable class implements IObservable interface correctly
• all tests pass yarn test

Issues:

• Closes: [libs/movex-core-util] Refactor Observable to implement IObservable #77
