accessibility issue: unable to organise requests and folder

### Expected Behavior

Screen reader user should able to organise the request-- move the requests into a folder and pull it out from a folder.

### Actual Behavior

Currently, I can press tab key to reach the requests and collection table. I also can create new folder using the keystroke ctrl+shift+n.
But, after folder created, I want to move requests in and out of the folder, there is no way to do so.
The drag and drop method is not accessible by screen reader users because screen reader entirely rely on keyboard access.

### Reproduction Steps

1. Open a collection.
2. press tab key until screen reader reads 'request and collection table'
3. we can up down arrow to move through the items in the table.
4. I can see the folder and requests in the table/list.
5. But, I want to move the requests into the folder, no way to accomplish this.

Start by reproducing the request and folder table workflow in Insomnia with a screen reader and keyboard only, then trace the existing drag-and-drop interaction for moving requests. Done means users can move requests into and out of folders without drag-and-drop, and the behavior works through the described keyboard navigation.
