[DOC] doc.md + `man 1 lsd` fail to list custom theme-ing

[ChiefMikeK]

🤔 manpages should list file(s) associated to the program near the bottom of the the page.
Please add the following section @ https://github.com/lsd-rs/lsd/blob/master/doc/lsd.md?plain=1#L167
PS; I don't know how well PANDOC formats Markdown links to Manpages! ……………………………………………………………………………………………………………………………
