Can a warforged have an integrated airship?

We know that Warforged can have a vehicle as their integrated tool. I had assumed that this had to be a land or water vehicle. However, the D&D beyond character generator lists “Vehicles (sea/air)” as a tool proficiency option. From my understanding, D&D beyond is a canon D&D source. If “Vehicles (sea/air)” is a canon tool proficiency option, this means that warforged can have an integrated airship.

So, RAW, can warforged have an integrated airship?

Note: I know that this is not RAI. My question is about strict RAW.
