py-check.mk: Run isort with "make format"

If /usr/bin/isort is found, run it during "make format" to get a
defined way the imports are sorted. tool.isort in pyproject.toml is
updated to match the other fixers.

Commit the fallout of this change. Running the other fixers alone
doesn't change the formatting, so this should be safe.
