LocalCluster docs give incorrect default value

[jacksund]

This isn't a bug, but just notification that there is a typo in the documentation for LocalCluster.

The docstr indicates that the default is 8786, when the actual default is 0.

Someone likely switched the default to 0 while testing and forgot to switch it back. nbd
