Confused about the documentation on VectorStoreVectorProperty.Dimensions Property

### Type of issue

Typo

### Description

For my use case, I would like the Dimensions to be retrieved from the IEmbeddingGenerator instead of having to define it, as I may have different embeddings generators. In the documentation, it is not clear what is meant by omitted in this sentence: "This property is required when creating collections, but can be omitted if not using that functionality. If not provided when trying to create a collection, create will fail."

An example would help.
