What happened in your environment?

I have an OCI layout that contains several tags, some are in format of FQDN. I can list the tags by running oras repo tags --oci-layout $dirName, for example:

$ oras repo tags --oci-layout ./repo
example.registry.com/foo:latest
test.com/bar:v1
v2

However, if I replace --oci-layout with --oci-layout-path like this, there will be an error:

$ oras repo tags --oci-layout-path ./repo
Error: "oras repo tags" requires exactly 1 argument but got 0
Usage: oras repo tags [flags] <name>
Please specify exactly 1 argument as the target repository to list tags from. Run "oras repo tags -h" for more options and examples

The right way is to add one more parameter as the repository name, which should be an empty string in this case:

oras repo tags --oci-layout-path ./repo ""
example.registry.com/foo:latest
test.com/bar:v1
v2

This UX is strange and not intuitive.

What did you expect to happen?

The --oci-layout=path flag may not be applicable to the oras repo tags command.

How can we reproduce it?

1. Run oras repo tags --oci-layout $dirName
2. Run oras repo tags --oci-layout-path $dirName ""
