Dumping profiles while using a profile generates non-sense output

[manchoz]

Describe the problem

While using profiles – especially in the case of a default one has been specified – --dump-profile generates a wrong output, in the sense that it completely forgets about the currently selected profile.

To reproduce

❯ ls
sketch_mar22a.ino  sketch.yaml

❯ cat sketch_mar22a.ino
#include <Arduino_JSON.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

❯ cat sketch.yaml
profiles:
  default:
    fqbn: arduino:renesas_portenta:portenta_c33
    platforms:
      - platform: arduino:renesas_portenta (1.1.0)
    libraries:
      - Arduino_JSON (0.2.0)

default_profile: default

Expected behavior

When using a profile, --dump-profile should output the configuration of the current profile.
