Provide an option to inherit the visibility of the source repository

## Description

We have been migrating from GHES to GHEC. Currently, we have to implement a wrapper tool of `gh gei` to pass the visibility of the source repository to the `--target-repo-visibility` option. It would be great if the tool has an option to inherit the repository visibility (private/internal) from GHES to GHEC, e.g., `--target-repo-visibility inherit`.
