Do you mind update Add-On to Add-on?
This is what we did in harvester PR

I feel like someone else above needs to approve this. Even though I'm okay with expanding the contractions and replacing things like & I don't know if others are okay with that. I guess worst case scenario we could always revert back if an issue arises.

LGTM for current translation change.

@a110605 I removed the existing labels changes and moved them in a separate PR for simplicity. Can you approve it again ?
