[MWRAPPER-117] Wrapper distributions and jars sha256 checksums should be published

**[Alexis Tual](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=atual)** opened **[MWRAPPER-117](https://issues.apache.org/jira/browse/MWRAPPER-117?redirect=false)** and commented

The Maven wrapper supports setting the sha256 for both the distribution and the wrapper jars: https://maven.apache.org/wrapper/#checksum-verification-of-downloaded-binaries.
However those sha256 checksums are not published in https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/ nor https://repo.maven.apache.org/maven2/org/apache/maven/wrapper/maven-wrapper making this feature harder to use.
