ruff format check lines-after-imports options but not respect it

[trim21]

I'm using ruff 0.6.5 (8558126df 2024-09-13) with config tool.ruff.lint.isort.lines-after-imports = 2

ruff format warns about lines-after-imports are not -1,1,2 but did't add 2 empty lines after last import

for example, not changes for this file:

import io

with io.StringIO() as f:
    print("ok", file=f)

The lines-after-imports setting is a isort setting and isort runs as part of ruff check and not ruff format.

Can you try to run

ruff check --fix --select I

It should add the two empty lines. We hope to integrate format into ruff check in the long-term and possibly move isort to format to reduce the confusion (see #8232)
