Switch to ruff

[adam-grant-hendry]

Context

flake8 takes a long time to run (i.e. pre-commit). It would be nicer to use ruff.

Proposal

1. Remove flake8 as a dependency, including the .flake8 file.
2. Add ruff rules to pyproject.toml file
3. Modify .pre-commit-config.yaml to use ruff

Tasks and updates

• Remove flake8 as a dependency, including the .flake8 file.
• Add ruff rules to pyproject.toml file
• Modify .pre-commit-config.yaml to use ruff

Makes sense to me - I think that @agoose77 recently updated to ruff on some other projects in EB as well.

@choldgraf @agoose77 flake8 takes the longest linting time, not black. Can we reopen this until we switch from flake8 to ruff?

[agoose77]

We should do both - let me check, I thought I'd removed flake8 but it's been a very long week...
