Idle HTTP Connection Timeout default is wrong

In the Idle HTTP Connection Timeout section the specified default is incorrect and should be 4.5s as it was since version 3.0.6 when it was changed from 30s to 4.5s
Release notes: https://docs.couchbase.com/java-sdk/current/project-docs/sdk-release-notes.html#version-3-0-6-14-july-2020

Name: Idle HTTP Connection Timeout
Builder Method: IoConfig.idleHttpConnectionTimeout(Duration)

Default: 30s

System Property: com.couchbase.env.io.idleHttpConnectionTimeout

The length of time an HTTP connection may remain idle before it is closed and removed from the pool. Durations longer than 50 seconds are not recommended, since some services have a 1 minute server side idle timeout.
