Add prompt to choose between opening JSON settings file or folder

[farheen-shaikh530]

Summary of the Pull Request

This PR introduces a confirmation dialog that allows users to choose between opening the settings JSON file or the containing folder. This enhances user flexibility when accessing configuration files from the terminal.

Motivation

Previously, clicking "Open JSON" would directly open the file. This change adds user choice, improving usability and matching expectations for broader editing or navigation workflows.

My thoughts: Why a content dialog and not a button with secondary conmand? A button with secondary command to open the folder feels much user friendlier.

Hi team, I've cleaned up the PR and removed unrelated .vcxproj changes. Now, it only includes the intended logic for adding the confirmation dialog to choose between opening the settings file or its folder. Ready for your review. Thanks again for the guidance!

Thank you for the feedback!
I agree that using a button with a secondary command could feel more seamless for users.
I initially went with a ContentDialog to align with how other prompts are handled in the Terminal UI and to make the choice explicit when clicking “Open JSON.” That said, I’m open to switching to a secondary command on the existing button if that better matches the UX expectations or existing UI patterns.
Let me know your thoughts — happy to iterate based on the team’s preference!

I can't decide this. Thoughts?

Hi @farheen-shaikh530. A few comments/questions:

• It looks like all of the changes are affecting just the vcxproj files. I'm not seeing any of the code adding the UI or new functionality. If this is correct, please update the PR title and body appropriately.
• The PR body says that this "Fixes [Feature Request] Option to auto trim leading/ending new lines/spaces from pasted content #14410", but that issue seems unrelated. Is there a different issue you meant to link /?

Thanks!
