Incorrect documentation for `--image-volume` option in podman run

There is an inconsistency in the documentation for the --image-volume option in the podman run command.

According to the official documentation (reference), the options listed are:

• bind
• tmpfs
• ignore

However, when attempting to use an invalid option in the command line, Podman returns an error that lists a different set of acceptable values:

[root@ec0d6d263855 tmp]# podman run -it --rm --image-volume=toerror myimage /bin/bash
Error: invalid image volume mode "toerror" required value: anonymous, tmpfs, ignore

So the correct option appears to be anonymous instead of bind as currently documented.

Please update the documentation or clarify if there is a difference between bind and anonymous.
