What's the issue?

watchdog 5.0 introduced a new signal that is fired when a file gets closed without any changes written.
This leads to random reloads when something opens and closes a file. opened events are already ignored, so we should ignore the new closed_no_write events too.

How to reproduce?

Update to watchdog 5.0+ and wait for the reloads to come in.

What's the expected behavior?

Werkzeug should only reload if there are actual changes to the code base.

Environment

• Python version: 3.11.2
• Werkzeug version: 3.0.4
