So, it looks like the underlying implementation supports this, but not sure if there's any UI that does. The Open As action on files currently configures this for all files without extension - could perhaps be extended there to offer other options?

Adding a file in the userdir at <userdir>/config/Services/MIMEResolver/user-defined-mime-resolver.xml with the following contents will work -

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE MIME-resolver PUBLIC "-//NetBeans//DTD MIME Resolver 1.1//EN" "http://www.netbeans.org/dtds/mime-resolver-1_1.dtd">
<MIME-resolver>
    <file>
        <name name="Jenkinsfile"/>
        <resolver mime="text/x-groovy"/>
    </file>
</MIME-resolver>
