Avoid extra parentheses in yield expressions (#7444)

## Summary

This is equivalent to https://github.com/astral-sh/ruff/pull/7424, but
for `yield` and `yield from` expressions. Specifically, we want to avoid
adding unnecessary extra parentheses for `yield expr` when `expr` itself
does not require parentheses.

## Test Plan

`cargo test`
