The [Advanced Annotation Vectors Tutorial](https://stumpy.readthedocs.io/en/latest/Tutorial_Advanced_Annotation_Vectors.html) links the previous tutorial, [Annotation Vectors Tutorial](https://stumpy.readthedocs.io/en/latest/Tutorial_Annotation_Vectors.html) in it a few times. The links are broken though, I forgot to add `.html` at the end there. All that needs to be done is add `.html` at the end of the links.
