Update image factory docs with new config

[rothgar]

The 1.0.0 release also doesn't require /dev or privileged permissions.

Fixed by #329

Do the arguments to the image factory still work? I thought I saw that it now takes a config file argument instead.

nope, they are removed

Should they be removed from https://github.com/siderolabs/docs/blob/main/public/omni/infrastructure-and-extensions/self-hosted/deploy-image-factory-on-prem.mdx?plain=1#L351-L362 ?

We'd need an example config to show people how to configure the new version too
