Small final change before merge :)

Don't worry about the hacktoberfest deadline - we will add the hacktoberfest-accepted label before it arrives.

Hey @loks0n,
Can we merge the PR before hacktoberfest so I can be eligible for the Appwrite swags?

Hey there! There were a lot of big PRs during this Hacktoberfest, and we wanted to give everyone ample time to collaborate with our engineering team. If you were able to merge your PRs during October, amazing. If it’s still not merged, don’t worry about it either. Either way, we’ve got your Hacktoberfest swag minted and ready to ship.

Please comment with your Discord username here so we can contact you about your shipping information to deliver your Hacktoberfest swag.
