Implement shortcut for renaming in FileChooser

### What Happened?

Pressing the F2 keyboard shortcut in the Filechooser to rename a file or folder doesn't do anything. For instance, when loading or saving a file in Code.

Right-clicking on the item and selecting "rename", however, works.

### Steps to Reproduce

1. The Filechooser window pops up whenever saving or opening a file
2. Select a file or folder to rename
3. Press F2
4. Nothing happens

### Expected Behavior

Pressing the F2 keyboard shortcut should make the file or folder editable to rename it.
