### Bug description
Attempting to use an external FTP storage with a non-standard port fails. This is due to FtpConnection:__construct() getting the port to use from the GUI as part of the hostname argument and using the raw value as is. While PHP's ftp connect functions expect the hostname and port to be separate arguments.
This can also be seen in the cli:
$sudo php ./occ files_external:config mount id hostname
example.com:1234
$sudo php ./occ files_external:config mount id port
null
$
This will cause the debug log to get a PHP error from either ftp_ssl_connect() or ftp_connect(): getaddrinfo failed: Name or service not known
### Steps to reproduce
1. Enable external storage support.
2. Add a new FTP or FTPS external storage configuration.
3. Specify the non-standard port in the host box [as per the instructions in the admin manual](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage/ftp.html).
4. Attempt to test the connection.
### Expected behavior
FTP connection test to succeed and the external storage to be usable.

```
### Additional info
As a workaround, manually setting the port for the external storage via the occ command on the CLI will allow the connection to work.
E.x.
$sudo php ./occ files_external:config mount_id host example.com
$sudo php ./occ files_external:config mount_id port 1234
