webp missing from DockerHub images

[gaaat98]

Describe the problem

In theory #2066 should have added the webp packages used by Dynmap for generating webp tiles, however it appears that for some reason the packages are not installed on the images downloaded via docker pull itzg/minecraft-server
After running the container, if I execute sudo docker exec -it mc webp the result is OCI runtime exec failed: exec failed: unable to start container process: exec: "webp": executable file not found in $PATH: unknown.

I tested this both on Unraid and Windows 11+WSL, am I doing something wrong?

Container definition

docker run  -e EULA=TRUE -d -p 25565:25565 --name mc -v /tmp/mc-data:/data itzg/minecraft-server

I removed webp since it added 200-300 MB to the image size. Please use an older image tag until I figure if/how I want to support that package. You're also welcome to build your own image that adds that package.
