What happened

When setting up an FTP connection with a custom port (different from 21), the FTP Hook does not read it at all and simply passes the hostname and uses the default port set by FTP_PORT in ftplib.FTP_PORT (used by ftplib.FTP.port), thus preventing any modification of default port 21.
PS: The 'connect' function of the FTP class reads port from the self.port attribute;

What you think should happen instead

The FTP Hook should be able to read the port (if set) and pass it to the FTP object created

How to reproduce

Set up any FTP connection with and test it on Airflow UI.
