cleanup: update references to /help/ that should now be /helptext/ I noticed this only because the WiX build was broken after 2e017696181f. I haven't tested this change with WiX, but it seems pretty obvious by inspection this should fix it. Differential Revision: https://phab.mercurial-scm.org/D7472

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
