Alpha2 flight - Add to demo.whitebox.aero

Description

We have a new flight to showcase, we should add it to https://demo.whitebox.aero/

Scope

• Use the data from the alpha2 flight to add it to the https://demo.whitebox.aero/ website, if possible without removing the previous one from the flight library.
• Update demo.whitebox.aero to the alpha2 version (also tag the release at the same time, if it hasn't already been done)
• If it isn't possible to keep the previous flight currently, create a ticket specifying the steps necessary to support this use case, and allow to easily share flights between instances as tgz
• If any data like video was not processed correctly, do the processing manually and correct the data as necessary. Post details about this in this feedback item or its resulting ticket: #498 (comment 3092749610)
• Outline the requirements to produce a {export,import}_flight command/functionality
