Bug Report

Current behavior

arduino-cli board details arduino:avr:una
Error getting board details: loading board data: board arduino:avr@1.8.3:una not found

When calling some commands that expect an FQBN the error returned is not clear if the board ID part of the FQBN doesn't exist for that platform.

Expected behavior

arduino-cli board details arduino:avr:una
Error getting board details: loading board data: board arduino:avr:una not found, did you mean arduino:avr:uno?

arduino-cli board details arduino:avr:una
Error getting board details: loading board data: board arduino:avr:una not found

A clearer error message should be shown, it would be cool if a suggestion could be made for the correct FQBN.

Environment

• CLI version (output of arduino-cli version): arduino-cli alpha Version: 0.18.3 Commit: d710b642
• OS and platform: doesn't matter

Additional context

None.
