Forbid empty string values for container id in commands

[YJDoc2]

Currently container_id is a required argument for all commands that require container_id, but there is no restriction that empty string value cannot be provided as container_id. For example :

youki --root (root_path) create --bundle (bundle path)

gives error, but

youki --root (root_path) create --bundle (bundle path) ""

does not, as (at least bash) passes "" as an empty string argument, and clap allows it, as it is a valid string value.
This PR adds forbid_empty_value to all container_id fields, which forces it to give an error message whenever empty string is provided.

Also, here changes job is not run even though there are changes in src/* file. this is probably due to
https://github.com/containers/youki/blob/main/.github/workflows/main.yml#L20
where the src/* is in quotes ('') due to which it does not match any path.
@utam0k @Furisto Should I try updating the workflow file in this PR only, or should I open a new PR for that?

Can I ask you for another PR?
