[PATCH] Add flake8 and isort to .pre-commit-config.yaml

[Tom Tromey <tromey@adacore.com>]

This adds flake8 and isort to .pre-commit-config.yaml.  This way, they
will automatically be run on commit.

I chose the most recent available versions after verifying that they
don't cause any reports or changes in the current tree.

Internally at AdaCore, we also use a few flake8 plugins as well, so
perhaps that's another avenue for investigation.
