Migrate to new Shipkit plugins (#419)

Migrate to new Shipkit plugins (#410 / #419)

Shipkit is deprecated and the GitHub project[1] is archived. They
write:

> "One Shipkit Gradle plugin to rule them all" approach has proven
> hard to maintain for the team. We [have] converted Shipkit into a
> narrow set of small libraries (design note[2]). Several customers,
> inclu[d]ing Mockito project have already migrated.

More preecisely, Shipkit was split into these projects:

* shipkit-auto-version[3]
* shipkit-changelog[4]
* shipkit-github-release (no source on GitHub?)

This change updates the build accordingly.

Closes: #410
Maybe solves: #256 (can't be determined without a release build)
PR: #419

 ### Versioning
 
-Shipkit manages versions by reading from and writing to [`version-properties`](version.properties):
-On each build, it releases the version specified by the `version` field and then increases its patch level for the next release.
+Shipkit manages versions by reading from [`version-properties`](version.properties):
+The variable `version` defines a _major_ and _minor_ version and leaves _patch_ undetermined (e.g. `1.3.*`), so Shipkit can pick the next version.
 
 This is how JUnit Pioneer handles versioning:
