mvn.py: Explicitly specify version in mvn deploy command
mvn.py: Explicitly specify version in mvn deploy command

When deploying to Maven Central via Sonatype it's OK to omit the
version from the command line and it just takes the version that's
specified in the generated pom.xml.

Some repositories, however, will reject the deploy in this case.

Update the deploy command to explicitly specify the version.

Note that we already do this for the install command.
