Linux arm 64 architecture is not detected

[juliabeliaeva]

get_google_supported_platform_string which detects the platform architecture to download the chrome build, ignores the arch_detected value on Linux systems. This results in incorrect chrome build being downloaded for aarch64.

	def get_google_supported_platform_string() -> str | None:
	arch_size_detected = "64" if sys.maxsize > 2**32 else "32"
	arch_detected = "arm" if platform.processor() == "arm" else "x"
	chrome_platform_detected: str | None = None
	if platform.system() == "Windows":
	chrome_platform_detected = "win" + arch_size_detected
	elif platform.system() == "Linux":
	chrome_platform_detected = "linux" + arch_size_detected
	elif platform.system() == "Darwin":
	chrome_platform_detected = "mac-" + arch_detected + arch_size_detected
	platform_string = ""
	if chrome_platform_detected in supported_platform_strings:
	platform_string = chrome_platform_detected
	return platform_string

Moreover, platform.processor() returns aarch64 and not arm on my machine, which results in wrong arch_detected value.
