build(docs): Update @fluid-tools/api-markdown-documenter

[Josmithr]

Updates API docs infra to accommodate API changes in the library. Most notably: custom transformation logic now targets mdast directly, rather than the bespoke documentation tree representation that has been removed from the library.

[Josmithr]

Note for reviewers: we were previously transforming tables directly to HTML so we could inject these styling properties, but they were not being respected to begin with. If we wish to add table hover behavior, we will want to implement that using standard styling practices.
