[Pkg-emacsen-addons] Bug#900305: Please add Recommends: elpa-imenu-list to enable document structure sidebar

Hi,

I just noticed that markdown-mode prominently advertises support for
imenu-list sidebars that display document structure
  https://jblevins.org/projects/markdown-mode/

and in my opinion that is an upstream recommendation for imenu-list.  Regrettably the project doesn't document how to replicate this layout, other than noting

  * markdown-nested-imenu-heading-index - Use nested imenu heading
    instead of a flat index (default: t). A nested index may provide
    more natural browsing from the menu, but a flat list may allow for
    faster keyboard navigation via tab completion.

  * markdown-add-footnotes-to-imenu - Add footnote definitions to the
    end of the imenu index (default: t).

in their README.md.

I'd be happy to commit the change to debian/control, and/or filing a
PR with upstream about documenting how to reproduce this layout.

Cheers,
Nicholas
