Prefix error messages with "❌"

[craicoverflow]

We could prefix all error messages with an "❌" emoji to replace the "Error" prefix.

$ rhoas kafka use --name kascfkadsfk
❌ Kafka instance "kascfkadsfk" not found. Run the command in verbose mode using the -v flag to see more information

This will enhance the visual output of the CLI.

I like it but we would probably need some community member with windows machine to do it considering CMD could have issues with some special unicode characters.

That is true.
