Document `rebase.forkpoint` in rebase man page

The configuration option `rebase.forkpoint' is only mentioned in the man page of git-config(1). Since it is a configuration for rebase, mention it in the documentation of rebase at the --fork-point/--no-fork-point section. This will help users set a preferred default for their workflow.
