PERF: Pass the -ping option to the identify ImageMagick command to speed it up (#25697)

Browse Source 
The `-ping` option significantly speeds up the ImageMagick `identify` command per our testing and the [documentation](https://imagemagick.org/script/command-line-options.php#ping):

> -ping
Efficiently determine these image characteristics: image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.). Use +ping to ensure accurate image properties.

We already pass the `-ping` option in other places where the `identify` command is used, so it makes sense to use the option everywhere.
