What happened in your environment?

I run oras tag -h and it shows wrong CLI example for tagging a manifest in an OCI image layout

> oras tag -h
Tag a manifest in a registry or an OCI image layout
...
Example - Tag the manifest 'v1.0.1' to 'v1.0.2' in an OCI image layout folder 'layout-dir':
  oras tag layout-dir:v1.0.1 v1.0.2
...

What did you expect to happen?

The example should be

Example - Tag the manifest 'v1.0.1' to 'v1.0.2' in an OCI image layout folder 'layout-dir':
  oras tag --oci-layout layout-dir:v1.0.1 v1.0.2

How can we reproduce it?

oras tag -h
