Real-time code changes cannot be detected in Docker. (--watch)

Summary: Ruff check --watch not working under Docker

Detailed information: I am developing using Docker+Poetry+Python, but I found the ruff check --watch mode does not detect file changes in real time when running under Docker.

Reproduction steps: Create a container image based on python:3.11-bullseye and run it in sleep infinity mode, use ruff check --watch to detect code changes in real time.

Version information: Ruff 0.0.261, Python 3.11-bullseye.

Start by reproducing `ruff check --watch` in a `python:3.11-bullseye` container, using the reported Ruff 0.0.261 setup, and compare file-change behavior with a non-container run. Done means changes to the watched source are detected in real time under Docker.
