Make it clear in the UI that "Delete" of file or folder is permanent
action.
For example in windows explorer and VS Code "Delete" means move to
trash.

Or maybe also remove permanent delete from the context menu completely
and allow it only through keyboard shortcut, like it's in Windows
Explorer, VS Code and KDE Dolphin file manager.

Release Notes:

- Improved wording within file deletion prompts in the projetct panel.
