docs: possible wrong anchor in a link

[raulwwq0]

I found the following link in core-concepts/getters.md: [previous section of state](./state.md#options-api). However this anchor doesn't exists in core-concepts/state.md. So it is supposed to be like that or should it be other anchor?

I guess it should be #usage-with-the-options-api because is where mapState() appears, but I want to confirm it first.
