Fix: Support all SSH private key formats in ssh-agent plugin

Browse source 
The previous implementation only supported OpenSSH private keys, which start with "-----BEGIN OPENSSH PRIVATE KEY-----". This commit improves the plugin to support all valid private key formats by using the 'file' command to identify them based on their content.

This change ensures that the ssh-agent plugin can handle keys in various formats, including PKCS#1, PKCS#8, and OpenSSH.
