Work around bazelbuild/stardoc#78.

Markdown bullet lists work fine in the general descriptions block of macros/rules/providers, but for rule attributes and provider fields the the markdown is a table, and `*` has no means (and stardoc transforms the content to remove newlines). The above issue is to support catch these and marking html bullet lists out of them, but until that is done, adding a blank line between each bullet gets slightly more readable generated/render documents.
