Version and Platform (required):

• Binary Ninja Version: 5.3.9265-dev Ultimate (564b14be)
• Edition: Ultimate
• OS: macOS
• OS Version: 26.3
• CPU Architecture: M1

Bug Description:
On macOS when the DSC plugin can't find the corresponding copy of DSC for a database the file explorer pops up but there's no indication to the user what Binary Ninja is expecting the user to open in the file explorer dialog.

Expected Behavior:
Something to indicate to the user why the file explorer is being displayed.

This should be fixed as of builds >= 5.4.9718-dev and I forgot to close it when my PR (#8188) was merged.
