fix(ssh): Ensure that the private key ends with a newline character (#1073)

Browse Source 
* fix(ssh): Ensure that the private key ends with a newline character

Fixes an issue where SSH private key files were not written with a newline character at the end, preventing parsing errors in certain SSH clients

Update the package

* fix(server_func_btns): Fixed an issue with the order of SSH command parameters and added file permission settings

Added permission settings for private key files on non-Windows platforms to ensure secure access. Additionally, the order of SSH command parameters was adjusted to ensure that connection parameters are passed correctly.
