docs: Fix ssh test command

[tyler36]

The Issue

The current command generates an error:

❯ ssh [email protected] [email protected]
Invalid command: [email protected]
You appear to be using ssh to clone a git:// URL.

Confirmed issues in the following terminals:

• PowerShell 7.4.6
• Windows Powershell 5.1.22621.4391
• Git bash 2.47.0.windows.2

How This PR Solves The Issue

Update the command.
Now generates the following:

❯  ssh [email protected]
Enter passphrase for key '/c/Users/XXXXXX/.ssh/id_ed25519':
Hi XXXXXX! You've successfully authenticated, but GitHub does not provide shell access.

Looking at https://docs.github.com/en/authentication/connecting-to-github-with-ssh/testing-your-ssh-connection, they recommend:
