Subject: [PATCH] Emit a `BreadcrumbsChanged` event when associated settings
 changed (#36177)

Closes https://github.com/zed-industries/zed/issues/36149

Release Notes:

- Fixed a bug where changing the `toolbar.breadcrumbs` setting didn't
immediately update the UI when saving the `settings.json` file.
