## Bug Report ### Current behavior ``` arduino-cli upload --fqbn arduino:avr:nano --programmer list ``` Fails to treat `list` as a special symbol. ### Expected behavior The documentation says it will list available programmers. ### Environment - CLI version (output of `arduino-cli version`): 0.13.0 - OS and platform: Windows 10 ### Additional context `arduino-cli burn-bootloader --fqbn arduino:avr:nano --programmer list` works as advertised. The capability to get a list of supported programmers is available from burn-bootloader, perhaps update the documentation to suggest that.
