Encountered issues have been fixed so we can remove the pinning of sphinx.

It is a common practice to open an external link in a new browser
tab so process external links with javascript when a documentation
page got loaded to enforce such behavior.

Corresponding RST document has been renamed to uri-scheme-swhids.rst
so add a redirection for URL backward compatibility.

With recent enough versions of setuptools/setuptools-scm, the pip
dependency resolver is now capable of sorting out our full dependency
tree. We can just install all packages at once (which does the
dependency resolution step once).

To speed up the process even more, inline the few "build" (setup.py)
dependencies to allow disabling build isolation (which creates a new
venv and installs setuptools-scm in it for every single package).

That hook can be frustrating as it can discard a long commit message
if it finds a typo in it so better removing it.

black is considered stable since release 22.1.0 and the version
we are currently using is quite outdated and not compatible with
click 8.1.0, so it is time to bump it to its latest stable release.

Please note that E501 pycodestyle warning related to line length
is replaced by B950 one from flake8-bugbear as recommended by black.

Without this, the actual documentation build will fail once a new package is
incompletely installed.

Do not generate TOC with sphinx-apidoc.

Mark the apidoc/swh.rst file as orphan.
