[Bug]: Bottle creation fails when using Games template

[JohnTheCoolingFan]

Describe the bug

When creating a bottle using Games template, the creation process fails and on the next launch of the bottles app I get the following error log:

[Errno 2] No such file or directory: '/home/USER/.var/app/com.usebottles.bottles/data/bottles/templates/c566283e-0a0b-413e-b3ae-96432c49cf21'  File "/app/share/bottles/bottles/backend/utils/threading.py", line 62, in __target
    result = self.task_func(*args, **kwargs)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File "/app/share/bottles/bottles/backend/managers/manager.py", line 1287, in create_bottle
    TemplateManager.unpack_template(template, config)

  File "/app/share/bottles/bottles/backend/managers/template.py", line 193, in unpack_template
    shutil.copytree(

  File "/usr/lib/python3.11/shutil.py", line 571, in copytree
    with os.scandir(src) as itr:
         ^^^^^^^^^^^^^^^

To Reproduce

1. Open the botles app
2. Create a new bottle using Games template
3. Watch it immediately fail
4. Close the errored bottle creation dialogue
5. Close and start the app again
6. Observe the reported crash message from previous launch
