Workaround Even Better TOML crash related to allOf (#15992)
## Summary

Fixes https://github.com/astral-sh/ruff/issues/15978

Even Better TOML doesn't support `allOf` well. In fact, it just crashes.

This PR works around this limitation by avoid using `allOf` in the
automatically
derived schema for the docstring formatting setting. 

### Alternatives

schemars introduces `allOf` whenver it sees a `$ref` alongside other
object properties
because this is no longer valid according to Draft 7. We could replace
the
visitor performing the rewrite but I prefer not to because replacing
`allOf` with `oneOf`
is only valid for objects that don't have any other `oneOf` or `anyOf`
schema.

## Test Plan

Ruff Formatter

The Ruff formatter is an extremely fast Python code formatter that ships as part of the ruff CLI.

Goals

The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff.

Specifically, the formatter is intended to emit near-identical output when run over Black-formatted code. When run over extensive Black-formatted projects like Django and Zulip, > 99.9% of lines are formatted identically. When migrating an existing project from Black to Ruff, you should expect to see a few differences on the margins, but the vast majority of your code should be unchanged.

If you identify deviations in your project, spot-check them against the intentional deviations enumerated below, as well as the unintentional deviations filed in the issue tracker. If you've identified a new deviation, please file an issue.

When run over non-Black-formatted code, the formatter makes some different decisions than Black, and so more deviations should be expected, especially around the treatment of end-of-line comments. For details, see Style Guide.
