config: drop the `format.exp-revlogv2.2` option

It is oddly named and not used at all. The one used by the code is still
`experimental.revlogv2`. So we drop that one option for consistency. We move
associate documentation to the actual option.

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