ol-options injection fails when plugin is not registered

[Fuzzyma]

Describe the bug
The docs state, that you can either register the plugin globally using app.use(OpenLayersMap /*, options */); or import the components as needed via import { Map, Layers, Sources } from "vue3-openlayers";.

However, when doing the later, the console is full with warnings that ol-options cant be injected.

Additional context

It is not entirely clear from the docs, if the plugin must still be registered even if using the explicit imports. However, I wonder why one would use explicit imports at all if the components are always globally available. The whole point is not to have global components when using the explicit import so it should just work like that.
