Update pre-commit hooks

[mcflugen]

I've updated the pre-commit hooks. In particular,

• Bumped all versions of pre-commit hooks.
• Remove the lint workflow. It was redundant since we use pre-commit.ci.
• Added isort and removed reorder-python-imports pre-commit hook. Annoyingly, black and reorder-python-imports conflict on style (black adds a blank line before imports) and this seemed to be the easiest solution.
