Add last successful build number as jenkins badge

:clipboard: **Description**

Please add a badge to display Jenkins last successful build number.

:link: **Data**

The data can be obtained by using the Jenkins API.
https://jenkinspath/job/jobname/api/json -> "lastSuccessfulBuild" -> "number"

:microphone: **Motivation**

This is a feature suggestion I previously asked for here: https://github.com/badges/shields/discussions/7039#discussioncomment-1384091

Start with the Jenkins API endpoint in the issue and inspect how existing Shields badges obtain and render external build data. The work is done when a Jenkins badge displays the value from lastSuccessfulBuild.number and the relevant badge behavior is covered by the project's tests.
