links to tutorial notebooks are not working!?

[ctb]

on https://sourmash.readthedocs.io/en/latest/tutorials.html#background-and-details, we have four tutorials:

The links to the first three are not working right: they are

https://sourmash.readthedocs.io/en/latest/tutorials.html#kmers-and-minhash.md
https://sourmash.readthedocs.io/en/latest/tutorials.html#sourmash-examples.md
https://sourmash.readthedocs.io/en/latest/tutorials.html#sourmash-collections.md

the fourth one is correct, but ...it's not a notebook?

https://sourmash.readthedocs.io/en/latest/tutorial-lin-taxonomy.html

So to me it looks like the notebook plugin isn't working right.
