Deprecate dead project #54

Is this project dead? I see no commits since September 2021. Consider deprecating and linking to fork https://github.com/cli/browser which is actively developed.

To deprecate a module, an author may add a // Deprecated: comment and tag a new release. The author may change or remove the deprecation message in a higher release.
