Subject: [PATCH] Fix docs typo for `ruff format` preview configuration (#8611)

## Summary

The ruff configuration section is called "format", rather than
"preview". Using the configuration as it was written in the docs gives
an error:

```
$ ruff format --check .
ruff failed
  Cause: TOML parse error at line 143, column 1
    |
143 | [tool.ruff.preview]
    | ^^^^^^^^^^^^^^^^^^^
invalid type: map, expected a boolean
```

## Test Plan

Tested running `ruff format` with the following in my `pyproject.toml`:

```toml
[tool.ruff.format]
preview = true
```

and it worked properly (using preview rules for formatting).
