Fix misleading in logging statement in parallelPipeline Method (#2566)

* Fix misleading in logging statement

* Update GitRepositoryRule.java

The original logging statement incorrectly logged the range of branch numbers as [1-(number + 1)], which implies that one more branch than specified is created. The update corrects this by logging the range as [1-number], matching the actual number of branches created in the loop.
