openzfs.github.io/openzfs-docs a few non working links

[slrslr]

At https://openzfs.github.io/openzfs-docs/man/v0.8/8/zfs.8.html#usedds is a single mention of a "usedds" that links to nowhere, no explanation on what that means. Same apply on neighbor items that are next to it. Can you please fix that?

https://github.com/openzfs/zfs/blob/zfs-0.8.6/man/man8/zfs.8 (but i think it may be more pages that has this issue)

In other cases (e.g. section headings, short option), clickable links are used simply to make it easier to refer directly to a place in the document by simply clicking on the link. The reference to usedds (and others listed with it) is consistent with the rest of the references in the manual.

I'm not sure if it's possible to create direct links to the descriptions of each property in the Native Properties section of zfsprops(7) 🤔

We already have a separate issue about adding abbreviations (shortened column names) in zfsprops(7): #14810.
