Make regular text in markdown comments wrap in notebook editors. (microsoft#224484)

Fixes microsoft#224483.

Without this, the comments inherit nowrap from monaco-list. I decided to fix it at this level because only in the notebook editor the comments seem to be ancestors of a monaco-list. I picked "initial" to indicate we are not actively trying to set anything, we are just trying to go back to normal, as the markdown renderer expects it.
