chore: Fix pre-commit config, fix linting

[aborgna-q]

The mypy step in pre-commit didn't get updated after the name change.

pre-commit run --all-files threw multiple errors, so I updated those too.
(I had to update the mypy check version to avoid some missing type errors).

I see that mypy and ruff are being run on the CI, but it might be nice to just run this pre-commit config there instead of separate checks.

Also, I noticed poetry install doesn't seem to install some necessary dependencies such as pytest, pytket and tket2. We should document those in the README under developer instructions. I am new to poetry, I wonder if it allows additional deps analogous to pip install .[dev] that we did before.

[aborgna-q]

There's a [tool.poetry.group.dev.dependencies] section for dev dependencies.

I think #118 adds tket2 as an optional dep. You need to pass --extras=pytket to poetry to install them.

[ss2165]

poetry install should install everything in the dev dependency group - CI relies on this.

We will add details about how to use all these extra dependencies with poetry in the README in a follow up PR
