Fix incorrect version label for OpenSSL pre-req

The "Java 12" tag was correct for the 0.13 release of Java 12, which proceeded

 removed.

Closes: #293

 If you obtain binaries from the AdoptOpenJDK community, the following pre-requisites are required:

The library is expected to be found on the system path. If you want to use OpenSSL cryptographic acceleration, you must install OpenSSL 1.0.2 or 1.1.X on your system. If the library is not found on the system path, the in-built Java crytographic implementation is used instead, which performs less well.
