Notifier events for labels

First Check

• I used the GitHub search to find a similar requests and didn't find it.
• Checked the tasks tagged issues and verified my feature is not covered

Please provide a concise description of the problem that would be addressed by this feature.

I maintain and use an app that automatically labels shopping list items.
If labels are added or removed I'd like to be able to react to the changes.

I think right now the only way to do that would be to periodically request all labels from the API. Since its not a thing that will change often that seems wasteful.

Please provide a concise description of the feature that would resolve your issue.

If there were a notifier for changes to labels, I wouldn't need to poll for label changes.

Please consider and list out some caveats or tradeoffs made in your design decision

Since there are already notifiers for tags and categories, I'm guessing adding one for labels wouldn't be much more of a maintenance burden. I'm happy to work on it

Yeah I don't see a problem with adding this. If you want to give it a go you're welcome to! As you said, should be more or less the same as how we handle tags/categories.
