Changelog

🤖 Generated by Copilot at ab47b24

This pull request adds the ability to filter settings by extension ID in the preferences UI. It introduces a new extensionId property to the ISettingSection interface and passes it from the extension configuration contributions to the PreferenceSettingsService class. It also improves the style of the overwritten preference indicator in the preferences.module.less file.
