Display endnote reference numbers in the html
This commit removes the numbers that displayed from the endnotes in the html:
https://gitlab.coko.foundation/wendell/XSweet/commit/733fe21c2cac83b71143ff06f32be9f7acbfea87
Currently, the notes at the end of the html are unnumbered, although they're linked properly to the inline note callouts. The notes at the end of the html should show with note numbers that correspond to the numbered note callouts. Since the note callouts are automatically renumbered, note numbers displayed with notes should be generated too, to ensure that they correlate properly to their callouts, work with footnotes, don't display as roman numerals, etc.
I've seen authors delete the automatic numbering and manually number the notes - I think that's for a person to clean up manually.
Would implementing this also require that it be scrubbed out again in Typescript? If so, I'll make an issue there as well.
