Subject: [PATCH] Remove `ecosystem_ci` flag from Ruff CLI (#12596)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

@zanieb noticed while we were discussing #12595 that this flag is now
unnecessary, so remove it and the flags which reference it.

## Test Plan

Question for maintainers: is there a test to add *or* remove here? (I’ve
opened this as a draft PR with that in view!)
