Search before asking

• I had searched in the issues and found no similar issues.

What happened

I find we cannot set fs.sftp.keyfile in sftp connector, this means we only support use username and password to create ssh connection, but I find in the source code, there exist fs.sftp.keyfile https://github.com/apache/seatunnel/blob/c23070919c8abde6e95e42c28095ca318dddc5e7/seatunnel-connectors-v2/connector-file/connector-file-sftp/src/main/java/org/apache/seatunnel/connectors/seatunnel/file/sftp/system/SFTPFileSystem.java#L120-L132

so this is a missing option?
