Add “Open a path in VS Code” (#163)

Although it is largely duplicated to “Open a file or directory
in the currently open VS Code window”, this workflow is still
valuable because:

- It uses `.` as the default `dir`, which is more common in
  development.
- It does not add any additional flags such as `-r`.
