the official skybox example is broken

[go-dockly]

tried to load the official skybox example.

The skybox.png does render fine onto the cube locally. However trying to useHdr:

panorama := rl.LoadTexture("dresden_square_1k.hdr")

results in the following error:

WARNING: IMAGE: Data format not supported

@go-dockly Just tried the example on desktop and it works.

To support HDR textures, they must be enabled on raylib config.h and rebuilt the library.

For platform web, it is already listed in #4682
