fix(tohtml): disable modeline #32822

Browse Source 
Problem:
Running :TOhtml with a file containing modeline may generate an invalid modeline in the output.

Solution:
Add `<!-- vim: set nomodeline: -->` to the output.
Use vi-compatible modeline format ("set foo:"), to avoid the trailing `-->` being treated as part of the modeline.
