devel/py-setuptools-scm: update to 8.0.4

Directory and PORTNAME changed to match normalised name in release
tarball; consumers updated to match.

Although setuptools itself is specified as a run dependency in the
Python package metadata, it is currently left out here to prevent
environment pollution until at least PR 270510 is committed.
Additionally, this version of setuptools-scm requires setuptools>=61,
which means this version is only meant for USE_PYTHON=pep517 ports
as all USE_PYTHON=distutils ports will switch to devel/py-setuptools58
also after PR 270510. science/py-emmet-core is switched to
devel/py-setuptools_scm7 accordingly, as it specifies setuptools-scm<8.
devel/py-{flit-scm,hatch-vcs} have ${PY_SETUPTOOLS} added to
RUN_DEPENDS to compensate.

textproc/py-markdown-include: Update to 0.8.1

* Switch back to PyPI as the sdist is available there again.
* Utilize the PEP517 build framework as well.

Changelog since 0.7.0:

https://github.com/cmacmackin/markdown-include/compare/v0.7.0...v0.8.1

all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

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.

textproc/py-markdown-include: Update to 0.7.0

* Switch to GitHub for a while as the new release isn't available
  as sdist at PyPI.

textproc/py-markdown-include: New port

This is an extension to Python-Markdown which provides an “include”
function, similar to that found in LaTeX (and also the C pre-processor
and Fortran).

It was originally written for a FORD (= FORtran Documenter) Fortran
auto-documentation generator.
