### ImageMagick version

7.1.1-19 AppImage

### Operating system

Linux

### Operating system, version and so on

Kubuntu 23.10

### Description

The jpeg xl delegate seems to be missing. 

    $ magick identify test.jxl
    identify: no decode delegate for this image format `JXL' @ error/constitute.c/ReadImage/746.`

Delegates from `magick -version`: `bzlib djvu fontconfig freetype heic jbig jng jp2 jpeg lcms lqr lzma openexr png raqm tiff webp x xml zlib`

`magick -list format` does not list anything for jxl.

My installed libjxl and libjxl-tools version is v0.7.0.

### Steps to Reproduce

1. Download the ImageMagick AppImage from https://imagemagick.org/archive/binaries/magick
2. Have a jxl file or create one with `cjxl`
3. Use `magick identify` on your jxl file.
