Bug#1013959: Upgrade package to latest upstream version

[Jérôme Charaoui]

Package: mockito
Version: 2.23.0-2
Severity: wishlist

Dear maintainer,

Please upgrade mockito to the latest version, 4.6.1.

The currently packaged version, 2.23.0, was released in 2018 and the 
upstream project has released many dozens of updates since then.

In particular, the current version is missing the JUnit Jupiter 
extension which is needed to runs the testsuite for a project I'm 
currently packaging in Debian, logstash-logback-encoder.

Thank you!
