fix(main/zsh): Fix zsh-newuser-install being run twice (#20787)

Zsh already automatically runs zsh-newuser-install as part of the
`newuser` module. Running it manually in the system zshrc caused it to
run twice.

Not previously caught due to `zsh-newuser-install` exiting if the terminal size is below 72x15
