Testing the SMTP hook fails due to invalid check

[omacchioni]

In function def test_connection(self) -> tuple[bool, str]::

airflow/providers/smtp/src/airflow/providers/smtp/hooks/smtp.py

Lines 303 to 305 in f68cb3e

	status = smtp_client.noop()
	if status == 250:
	return True, "Connection successfully tested"

If I'm not mistaken, noop returns a tuple with (status_code, message) like this:

(250, b'2.0.0 Ok')

This is more or less documented in https://docs.python.org/3/library/smtplib.html

The test fails because it's only considering an int as a return value.
