docs: fix Terminal look README — clarify automatic shell change

README.md line 95 incorrectly claimed shell change ("chsh") only happens
"unless you confirm the interactive prompt." In reality, chsh_to_zsh()
unconditionally switches to zsh when invoked, with no separate whiptail
confirmation for this step. The only confirmation is at component and
look-picker level; once Terminal look is selected, the shell change
is automatic.

Rewrote the bullet to accurately reflect this: "Automatically changes
your login shell to zsh via chsh (if not already zsh) — once Terminal
look is selected and a prompt style is chosen, the shell change
happens automatically as part of applying the configuration."
