Uno WiFi Rev2 advertised as having OTA

A complaint that's been made repeatedly on the Arduino Forum about the Uno WiFi Rev2 is that it was advertised as having OTA upload capabilities, but then the buyers discover this is not supported:

~~AFAIK, the only place in Arduino's documentation where this claim remains is here:~~

UPDATE: fixed!

Several of Arduino's official distributors also have the OTA claim in their product listings for the Uno WiFi Rev2, which were likely based on Arduino's documentation before the OTA claim was removed. Here is an incomplete list:

Review the Arduino Forum reports, the archived Project Hub reference, and the distributor listings linked in the issue. Confirm which OTA claims remain inaccurate and coordinate corrections or updates to the affected documentation and product listings; done means the misleading claim is removed or corrected wherever Arduino controls it.
