Small bug report in git restore -p prompt

> cee6cb7300 (built-in add -p: implement the "worktree" patch modes,
> 2019-12-21) added the worktree patch modes to the built-in add -p.
> Its commit message claims to be a port of 2f0896ec3ad4 (restore:
> support --patch, 2019-04-25), which did the same for the script
> git-add--interactive.perl.
>
> The script mentioned only the worktree in its prompt messages in
> worktree mode, while the built-in mentions the worktree and also the
> index, even though the command doesn't actually affect the index.
>
> 2c8bd8471a (checkout -p: handle new files correctly, 2020-05-27)
> added new prompt messages for addition that also mention the index in
> worktree mode in the built-in, but not in the script.
>
> Correct these prompts to state that only the worktree will be affected.
