Use default pull request template

Use default pull request template

The more detailed pull request template in this plugin has been ignored by most recent contributors to the plugin, including me. Let's use the default pull request template so that the template is consistent with the other templates used in Jenkins plugins.

This is consistent with the plugin archetype. It also relies on the default pull request template rather than providing its own pull request template.

No automated tests because this is a change to infrastructure, not to production code.

What has been done

1. Removed the custom pull request template

How to test

1. Create a pull request and confirm that the default Jenkins pull request template is used
