Extension install should not have a default selection prompt

[weikanglim]

Describe the bug

Command Name
az containerapp --help without containerapp extension installed prompted me to install software. The software installation prompt had a default value. I accidentally pressed Enter and ended up installing the wrong software.

Errors:
No errors.

To Reproduce:

• Uninstall containerapp extension if you already have it installed
• az containerapp --help
• The UI prompt comes up for the installation suggestion. The prompt has a default choice selected. I accidentally pressed 'Enter' since it took 4 seconds for the installation suggestion to come up (was trying to type a second command). This ended up installing the wrong software.

Expected Behavior

An auto-suggested installation prompt should not provide a default choice selected.

1. Selecting the wrong selection ends up installing the wrong software
2. It is an auto-suggested prompt. High chances that it may not be right?

Side note: This did not reproduce consistently, but I expect az containerapp --help to be a direct match for containerapp and should always be recommended over other fuzzy matches.

Hi @weikanglim,

2.47.0 is not the latest Azure CLI(2.48.1).

Please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.
