[Bug]: bottles-cli run crashes if you don't specify either --executable or --program

[guihkx]

Describe the bug

I was trying to figure out how to invoke bottles-cli run, and I accidentally made it crash when I didn't specify either --executable or --program.

To Reproduce

$ flatpak run --command=bottles-cli com.usebottles.bottles run -b Default
05:35:27 (INFO) Forcing offline mode 
Traceback (most recent call last):
  File "/app/bin/bottles-cli", line 764, in <module>
    cli = CLI()
          ^^^^^
  File "/app/bin/bottles-cli", line 236, in __init__
    self.__process_args()
  File "/app/bin/bottles-cli", line 285, in __process_args
    self.run_program()
  File "/app/bin/bottles-cli", line 687, in run_program
    _executable = _executable.replace("file://", "")
                  ^^^^^^^^^^^^^^^^^^^
