Log error of exporting map file or tileset file

[snagasawa]

Hi, thank you to develop such a great tool ! :)

I tried to export map to tscn file by CLI and got failed, then a defailed message wasn't printed.
I added logging error message, now it can do that.

./Tiled --export-map main.tmx main.tscn --embed-tilesets

Failed to export map to target file.
Could not find .godot project in file path for file /Users/username/src/github.com/snagasawa/tiled-export-to-godot-sample/images/sample.png

environment:

• OS: MacOS v14.3 sonoma
• tiled: v1.11.0

Hey @snagasawa, the change looks good, thanks!

Can you apply the same change to the tileset export blow? The code is unfortunately a bit duplicated.
