Current Behavior

Right now, the Jenkins Pipeline detection solely relies on the existence of JENKINS_URL variable. Per the Jenkins docs:

(NOTE: only available if Jenkins URL set in "System Configuration")

For users that don't configure the Jenkins URL for their CI pipeline, this package returns a false negative.

Expected Behavior

This package should always return true for Jenkins CI, so I propose adding a check for the BUILD_ID variable as an additional check for Jenkins since that value should always be there in Jenkins CI. This is what ci-info does: https://github.com/watson/ci-info/blob/master/vendors.json#L135
