Document different ways to create a pipeline (#10762)

* Document different ways to create a pipeline: moved up/slightly modified paragraph on pipeline creation.

* Document different ways to create a pipeline: changed Finnish to Ukrainian in example for language without trained pipeline.

* Document different ways to create a pipeline: added explanation of blank pipeline.

* Document different ways to create a pipeline: exchanged Ukrainian with Yoruba.

+languages that don't yet come with a trained pipeline, you have to import them

+A blank pipeline is typically just a tokenizer. You might want to create a blank
+pipeline when you only need a tokenizer, when you want to add more components
+from scratch, or for testing purposes. Initializing the language object directly
+yields the same result as generating it using `spacy.blank()`. In both cases the
+default configuration for the chosen language is loaded, and no pretrained
+components will be available.
