Jenkins post receive hook stop working with Git Plugin 4.11.4

[TDesjardins]

With Jenkins Git Plugin 4.11.4 the HTTP notify calls needs a token to trigger a build (See https://www.jenkins.io/security/advisory/2022-07-27/#SECURITY-284). It can be created in "Git plugin notifyCommit access tokens" section of the "Configure Global Security" page.
To solve this issue the following script can be extended with a token parameter:
https://github.com/gitblit/gitblit/blob/master/src/main/distrib/data/groovy/jenkins.groovy

I can provide a PR if this is wanted.

A current workaround is to disable access token mechanism in Jenkins with the system property hudson.plugins.git.GitStatus.NOTIFY_COMMIT_ACCESS_CONTROL. But this option is insecure and is not recommended.
