*: Revise USES=python:... version range constraints

and strip all lower bounds of 3.9 or 3.10 because they are implied now.

python:3.9-X  -> python:-X
python:3.9+   -> python
python:3.10-X -> python:-X
python:3.10+  -> python
(options such as ,build preserved)

*/*: switch dependency from devel/py-lxml5 to devel/py-lxml

Currently, there are two versions of python XML processing library
which conflict each other in the ports tree, namely:
- devel/py-lxml5 (now at version 5.4.0)
- devel/py-lxml  (now at version 6.0.1)

To avoid the situation that some ports depend on py-lxml5 and some
others do on py-lxml (by switching dependencies individually), this
commit switches the dependencies from py-lxml5 to py-lxml at once.

Additional note: There are still two ports (textproc/py-rdflib and
www/py-draftjs-exporter) depending on py-lxml5 since they limit upper
version to less than 6.

*/*: update dependency on devel/py-lxml to devel/py-lxml5 (2nd attempt)

This is a follow up to the commit 230fb2661c78, which updated some
ports' dependencies on devel/py-lxml to devel/py-lxml5. It was an
attempt to follow the dependency change of
www/py-beautifulsoup. However, the switch was incomplete and broke
some other ports.

It has turned out that the ports depending on devel/py-lxml (at
version 4.9.3) does not limit their dependencies' upper bound to 4.x
except for one (devel/py-pymaven-patch). So updating them to
devel/py-lxml5 (at version 5.4.0) should cause no harm.

This commit switch dependencies of all the ports (except
devel/py-pymaven-patch) to devel/py-lxml5 avoid potential conflicts.

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.

Approved by:		portmgr (tcberner)

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.
