Update frameworks/zsh4humans.zsh

Disable prompt asking to change shell. Otherwise the GitHub Action fails
after the following output from zsh4humans:

    z4h: login shell isn't the same as this shell

      user         root
      login shell  /bin/sh
      this shell   /bin/zsh

    Change login shell of root to /bin/zsh?

      (y)  Yes. Recommended.
      (n)  No.
