fails with clean latest ports tree and all supported ruby versions.

Mk/**ruby.mk: Switch from USE_RUBY=yes to USES=ruby

Switch from Mk/bsd.ruby.mk to Mk/Uses/ruby.mk

Notable changes are.

- Mk/bsd.ruby.mk is moved to Mk/Uses/ruby.mk.
- USE_RUBY=yes is replaced with USES=ruby.
- USE_RUBY_EXTCONF is replaced with USES=ruby:extconf.
- USE_RUBY_RDOC is replaced with USES=ruby:rdoc.
- USE_RUBY_SETUP is replaces with USES=ruby:setup.
- RUBY_NO_BUILD_DEPENDS and RUBY_NO_RUN_DEPENDS are replaced with
  USES=ruby:{build,none,run}.
- RUBY_REQUIRE isn't used anywhere, so removed.
- USES=gem now implies USES=ruby.

This is mainly the work of yasu@ at https://reviews.freebsd.org/D27863

I have just made some cosmetic changes and ran exp-run to test that the
tree is not in a BROKEN state.

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.

devel: remove 'Created by' lines

devel/rubygem-omnibus: Update to 8.3.2

Changes:	https://github.com/chef/omnibus/releases
		https://github.com/chef/omnibus/blob/main/CHANGELOG.md

devel/ruby-gems: Update to 3.3.7

These are fixes Ruby 3.0

Changes were compiled against all dependencies of devel/ruby-gems and
they all built cleanly.

There are five known build failures, all prexisting:

* devel/rubygem-xdg5: requires Ruby 3.0
* devel/rubygem-xdg: requires Ruby 3.1
* graphics/rubygem-objectdetect: port explicitly marked broken
* mail/rubygem-tmail: port explicitly marked broken
* science/cdcl: marked broken, unfetchable

Plus, science/rubygem-ruby-dcl gets skipped because of science/cdcl

devel/rubygem-omnibus: Add rubygem-omnibus 8.2.2

Omnibus is a framework for building self-installing, full-stack software builds.
Omnibus provides both a DSL for defining Omnibus projects for your software, as
well as a command-line tool for generating installer artifacts from that
definition.
