*/*: Refactor java/openjdk7 removal

- java/openjdk7* has been removed from the tree since 2022-09-03 however
  the relevant codebases in bsd.java.mk has not been removed and the
  consumers has also not been updated to use the next jdk version. This
  commit updates all relevant consumers to use JAVA_VERSION=8 instead of
  JAVA_VERSION=1.7
- Since the introduction of jdk version 18 it looks like similar with
  jdk version 8(java version string 1.8). This is prone to error as it
  looks similar and is only seperated by a '.'. Remove using
  JAVA_VERSION with dotted fomat of java version string and update all
  consumers to utilize version 8 instead of 1.8.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Adjust to proposed changes in Java versioning

* Bug #238758 proposes to change the Java versioning from versions such
