"quarto add extension" installs extension after cancelling

[andrewheiss]

Bug description

Responding "No" to installing an extension still installs the extension

Steps to reproduce

1. Run this in a terminal (tested in zsh and bash):

   quarto add andrewheiss/quarto-wordcount

2. Respond "Yes" to "Do you trust the authors of this extension"

3. Respond "No" to "Would you like to continue"

4. Check the working directory—the extension is installed

Actual behavior

The extension is installed after responding "No" to not install it

Expected behavior

It probably shouldn't be installed after telling it to not to :)

Your environment

• macOS Sequoia 15.4.1
• zsh and bash
