few broken artifacts in jenkins' maven repo

[nicolas de loof]

Doing some work related to plugin management, I noticed some minor issues with repo.jenkins-ci.org

https://repo.jenkins-ci.org/public/org/jenkins-ci/plugins/job-dsl/1.33/job-dsl-1.33.hpi is actually a pom.xml

https://repo.jenkins-ci.org/public/org/jenkins-ci/plugins/bitbucket-build-status-notifier/1.3.2/bitbucket-build-status-notifier-1.3.2.hpi is actually a text file "target/bitbucket-build-status-notifier.hpi"

build-configurator-1.0.6.0.hpi is listed on https://repo.jenkins-ci.org/public/com/amcbridge/build-configurator/1.0.6.0/ but not available (404)
