[Bug]: Add docker.io to docker run command

[avnf]

What happened?

Hello
I suggest adding docker.io prefix to docker run command, this will improve compatibility with podman-docker (ubuntu 24.04)
I used
croc() { [ $# -eq 0 ] && set -- ""; docker run --rm -it --user "$(id -u):$(id -g)" -v "$(pwd):/c" -v "$HOME/.config/croc:/.config/croc" -w /c -e CROC_SECRET schollz/croc "$@"; } and had error
Error: short-name "schollz/croc" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"
... docker run --rm -it ... docker.io/schollz/croc

Also first run with croc() + docker (in case of that podman-docker) with docker.io/schollz/croc has a error '.config/croc: no such file or directory'

What did you expect to happen?

Use docker.io/schollz/croc in croc() option to start tool.
Document that .config/croc should be created in that way of running croc.

Steps to reproduce

1. ubuntu 24.04
2. sudo apt install podman-docker
3. croc() { [ $# -eq 0 ] && set -- ""; docker run --rm -it --user "$(id -u):$(id -g)" -v "$(pwd):/c" -v "$HOME/.config/croc:/.config/croc" -w /c -e CROC_SECRET schollz/croc "$@"; }
4. Error: short-name "schollz/croc" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"
5. croc() { [ $# -eq 0 ] && set -- ""; docker run --rm -it --user "$(id -u):$(id -g)" -v "$(pwd):/c" -v "$HOME/.config/croc:/.config/croc" -w /c -e CROC_SECRET docker.io/schollz/croc "$@"; }
6. Error: statfs /home/User/.config/croc: no such file or directory
