Convert setup.cfg to pyproject.toml, update tools

[braingram]

Move configuration in setup.cfg to pyproject.toml.

Use ruff to replace flake8, isort and bandit.

Update tools to otherwise more closely match asdf (pre-commit config, rules, codespell, etc).

Python 3.12 testing was added. The tests are currently passing and a claim for 3.12 support was added to pyproject.toml.

During this update a few things were noticed:

jinja

jinja is used to perform formatting for one string:

sphinx-asdf/sphinx_asdf/nodes.py

Line 2 in d81d949

from jinja2 import Environment

It is not listed as a dependency. This PR removes the use of jinja and replaces it with built-in python string formatting.

rename instead of refname

In directives.py ruff removed an unused variable rename.

sphinx-asdf/sphinx_asdf/directives.py

Lines 210 to 213 in d81d949

	elif shorten:
	rename = schema_id
	return refname, schema_id + fragment

This appears to be a typo (which was likely intended to be refname). However, switching this to refname results in build errors. I opened an issue for this (see: #81). For the scope of this PR the unused rename is replaced with a pass.

numpy

An attempt is made in conf.py to seed the numpy random number generated.

sphinx-asdf/sphinx_asdf/conf.py

Lines 9 to 13 in d81d949

	# Ensure documentation examples are determinstically random.
	try:
	numpy.random.seed(int(os.environ["SOURCE_DATE_EPOCH"]))
	except KeyError:
	pass

The used environment variable is not defined on readthedocs and makes this seeding unused for readthedocs builds. This PR removes this unused seeding.

datetime import in conf.py

datetime is imported by unused in conf.py. Asdf (and possibly other downstream packages) expect datetime to be imported when conf.py is star imported. A note and noqa was added to this import however the downstream packages should likely be updated to not expect this import or even better to not use a star import of conf.py.
