Shared Windows/WSL SSH/GPG key agents

By default, SSH and GPG key agents are not shared between Windows and WSL.

This means that by default if your SSH/GPG keys are encrypted with a password, you will be prompted for them each time unless you add them a key agent on both Windows and WSL.

Using win-gpg-agent allows you to add your SSH and GPG keys to the agent and also allows you to save your password, so that you don't need to enter it each time for each platform or after a restart. While keeping it secured via password encryption on disk and protected by your Windows account.

Disable Windows ssh-agent (if enabled)
