Improving the flow for adding the context in extension

[ghost]

Describe the improvement

• After adding a file (context) to DevChat, there is an icon which shows # of files (contexts) added. The icon resembles popular "add attachment" action.
• Hence, the user might end up assuming to add more contexts. But currently, users can only view or remove the contexts. I believe an improvement to "add more context" can help improve the user experience.

To Reproduce

Steps to reproduce the behavior:

0. Select a file > Right Click > Add to DevChat

1. Click on 'Context' icon in the prompt bar

2. Currently we can remove the context but have to go to step-0 to add it again

Suggested Solution

• There can be a way where a user can navigate to step-0

• or alternatively some instructions should help to remind the user to go back to step-0

• Also Ant design has a folder icon which might be better for this action
