Change the terminal ouput to be platform independent when creating an ssh key

[astroDimitrios]

How could the content be improved?

For instance in 3.1 the first output block shows:

Generating public/private ed25519 key pair.
Enter file in which to save the key (/c/Users/Alfredo/.ssh/id_ed25519):

we suggest changing the path to:

Enter file in which to save the key (~/.ssh/id_ed25519):

in all instances where there are /c/Users/Alfredo/ in the lesson episode.

Which part of the content does your suggestion apply to?
