Formatting code in docstrings

[john-science]

What is the change? Why is it being made?

Here I institute a new ruff rule so the example code in our docstrings matches the formatting and linting rules in the rest of the case base. It's not a hugely important change, but I feel it makes things cleaner.

NOTE: This is a docstring-only change.
