createFolderWithItems has not yet been implemented.

## What did you do?

- I right clicked on a query on the left pane in the "Queries" section
- I clicked "New Folder with Selection" in the dropdown menu

## What did you expect to happen?

I expected to be able to create a new folder for this query. I assumed it would create a new folder and prompt me for a name for the query or at least create a folder named "New Folder" with this query under it.

## What actually happened?

- I received this error message: `createFolderWithItems has not yet been implemented.`

## What software versions are you using?

Postico version: `2.0.4`

macOS version: `13.5.2`
(selecting "About this Mac" from the Apple menu)

PostgreSQL version: `14.7`

Start by locating the createFolderWithItems entry point behind the Queries section's “New Folder with Selection” menu action. Reproduce the action in Postico 2.0.4 and trace the existing folder and query-selection behavior; done means creating a folder, assigning the selected query to it, and prompting for a name or using “New Folder”.
