gh-42145: Set ruff format quote-style to preserve
    
We have not adopted a strict rule throughout the project on using `'`
versus `"` for quotes. This PR changes our ruff configuration to leave
quotes alone, so that developers can use `ruff format` without creating
large diffs that mostly just change `'` to `"`. If we ever decide to
enforce either single or double quotes, we can just change this config
option then.

Hopefully this makes it easier to use `ruff format` more often when
developing Sage without cluttering diffs.
