databases/sqldeveloper: limit Java version to 11 and 17

The Java versions supported by this port are in range from 11 to 17. The default
is 11. Add DEFAULT_VERSIONS+=java=N to /etc/make.conf if you want to use Java
"N", but all Java ports will also be affected. Or add SQLDEVELOPER_JAVA_VERSION=N
to /etc/make.conf if you want to override the Java version for this port only.
