[Bug]: external storage support default port for sftp broken

[Thernamyte]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.

Bug description

after update to 32.0.6 external storage support throws this error:

TypeError: fsockopen(): Argument #2 ($port) must be of type int, string given in $WEBROOT/public_html/3rdparty/phpseclib/phpseclib/phpseclib/Net/SSH2.php:1309

if port is supplied manually (22) this is resolved

Steps to reproduce

1. activate external storage support
2. add (valid) sftp
3. don't fill port (assume default 22)
