Release 0.4.3 version of microcks-testcontainers-java

[lbroudoux]

Tag on GitHub and push jars on Maven Central

This needed to be done after the release of Microcks 1.13.2 because we depend on microcks/microcks#1881

Now done. See release notes here: https://github.com/microcks/microcks-testcontainers-java/releases/tag/0.4.3
