DOC: configuration: fix alphabetical ordering for tune.pool-{high,low}-fd-ratio

In addition they were in the wrong alphabetical order in the doc. They
were added in 2.0 by commit 88698d966 ("MEDIUM: connections: Add a way
to control the number of idling connections.") so this must be backported
to 2.0.
