Lint all toolkits (#183)
# PR Description
* Adds/updates the following files to all toolkits:
    - `.pre-commit-config.yaml`
    - `.ruff.toml`
    - `LICENSE`
    - `Makefile`
    - `pyproject.toml`
* Lint all toolkits such that they pass `make check` and `make test` (a
total doozy). This includes adding some unit tests and evals.
* Github workflow for testing toolkits before merge into main (courtesy
of @sdreyer)
* Added a QOL improvement for tool developers for when they need to get
the context's auth token.
* Minor updates to `arcade new` template.
