SSH key simplify

Fixes https://github.com/lewagon/teachers/issues/3069

Note:

• The instructions for using the ssh connection in VS Code for Windows are not updated yet. The instructions on that part are currently only valid for MacOS. I haven't figured out a sufficiently easy similar thing for Windows yet.
• That said: that should not withhold us from bringing in the other changes which are a definite improvement for all, even if this last thing is not yet solved.

Yeah I see the issue, the SSH VSCode setup is indeed very unix-like heavy. It probably deserves separate expanded instructions for Windows - drop downs based on OS or additional bullet points for clarity.

Agree that we should just use a key named de-bootcamp for the bootcamp. It's relatively common that students already have an existing id_ed25519 key.

I'll add an mkdir -p ~/.ssh to create the folder on unix-likes for students that don't have it. I might play around in my windows partition to find the powershell equivalent.

Don't have my Windows laptop at hand now, but in PowerShell it's probably as easy as putting in backslashes instead of slashes. I think they made it as a convenience function. Not sure about the -p option. So mkdir ~\.ssh should suffice: ~ exists anyway, and if the folder already exists that's ok.
