[verona.stage] RFR 8087203: Adapt Version.java.template to the JEP-223 new version string format

[Alejandro E Murillo]

Please review these changes:

Bug: https://bugs.openjdk.java.net/browse/JDK-8087203
Webrev: http://cr.openjdk.java.net/~amurillo/9/8087203/

The actual code changes for this bug (8087203) were entered along
with the ones for 8087202. The changes here are just fixing some
javadoc comments in that template

Thanks
