Describe the bug

There is an error when importing the json exported by spine4.2. I hope Gdevelop can support Spine4.2 version. Because I hope to donate some of the funds earned after my game is released to Gdevelop, and the functions of Spine4.2 are very important in making some dynamic image games.

Steps to reproduce

Importing the json created by Spine4.2 will result in the following error

GDevelop platform

Desktop

GDevelop version

The latest

Platform info

Windows

Additional context

No response

There is another problem. The Spine plugin in GDevelop cannot use skins. As long as there is a skin in the imported json, the image will not be displayed.

At the moment, only Pixi Spine 4.0 is supported.
In order to upgrade, multiple things need to happen:

• upgrade to Pixi 7.4.2 -> Upgrade pixi to 7.4.2 #7190
• switch Pixi spine library to official one -> Apply the Spine Runtimes license to the Spine extension #6679 (comment)

The upgrade is not planned in the short future at the moment
