## Summary
This PR removes most of the syntax errors from the test cases. This
would create noise when https://github.com/astral-sh/ruff/pull/11901 is
complete. These syntax errors are also just noise for the test itself.
## Test Plan
Update the snapshots and verify that they're still the same.

## Summary
Fix `E231` bug: Inconsistent catch compared to pycodestyle, such as when
dict nested in list. Resolves#10113.
## Test Plan
Example from #10113 added to test fixture.
## Summary
We were considering the `{` within an f-string to be a left brace, which
caused the "space-after-colon" rule to trigger incorrectly.
Closes https://github.com/astral-sh/ruff/issues/8299.
