fdiagnostics-color in extra_flags causes break in library resolver

[Electro707]

Describe the problem

When -fdiagnostics-color=always is added as part of the build extra flags, the library resolver/processor is unable to resolve any libraries.

This is because, if I copy the output to the clipboard, the resolver seems to include the ANSI escape code in the library name:

To reproduce

with an example sketch such as

#include <Arduino.h>
#include <SPI.h>

void setup(void){
    Serial.begin(115200);
    Serial.println("HI!");
}

void loop(void){

}

run

arduino-cli compile -v \
	--build-property "compiler.c.extra_flags=-fdiagnostics-color=always" \
	--build-property "compiler.cpp.extra_flags=-fdiagnostics-color=always" \
	--fqbn ArduinoCore-avr:avr:uno \
	testArduinoCliBug.ino

Expected behavior

The ANSI sequence should be escaped/removed from the library

Arduino CLI version

Operating system version

Arch Linux

Additional context

From initial code research the most likely candidate for the fault is in internal/arduino/builder/internal/detector/detector.go, possibly in the function IncludesFinderWithRegExp or the thing calling it.
