Runs a simple text-based wizard that logs into GoFigr, generates or verifies an API key, lets the user choose a default workspace, and then writes a configuration file to `~/.gofigr`. This configuration is used by `gofigr_client()` when explicit credentials are not provided.
gfconfig(max_attempts = 3)Invisibly returns `NULL`. The main effect is writing configuration to disk and printing progress messages.
Maximum number of password/API key attempts before the wizard aborts with an error.
