Remove outdated documentation bits concerning -Wmissing-methods

In commit 503219e3e1667ac39607021b2d9586260fbab32b, we
stopped suppressing `-Wmissing-methods` warnings on class methods
whose names begin with an underscore. However, it seems the users'
guide documentation concerning this was never updated. Let's do so.

Test Plan: Read it
