*/*: 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.

misc/py-cppman: add port: C++ 98/11/14/17/20 manual pages on the terminal

Cppman is a tool that provides C++ manual pages on the terminal. It
acts as a convenient interface to view formatted C++ documentation
directly from cplusplus.com and cppreference.com, allowing developers
to access relevant information quickly without switching to a web
browser.

Features:
- Supports two backends (switch it with cppman -s):
  cplusplus.com
  cppreference.com
- Syntax highlighting support for sections and example source code.
- Usage/Interface similar to the 'man' command
- Hyperlink between manpages (only available when pager=vim)
  - Press Ctrl-] when cursor is on keyword to go forward and Ctrl-T to
    go backward.
  - You can also double-click on keyword to go forward and right-click
    to go backward.
- Frequently update to support cplusplus.com.
