Update setup instructions

[sjspielman]

Closes #155

This PR updates setup instructions for OpenRRP. I've commented out the previous setup instructions, and replaced them with instructions containing OpenScPCA links. I'm opening this a draft PR because WSL 2 instructions aren't yet live (so many links are empty for the time being), but this can still be reviewed for content in the meantime.

This looks good, but we should probably have something here about AWS setup as well. Or at least a placeholder for it?

Can you clarify this a little bit? I'm not thinking of what AWS setup steps they'd have to do* before coming to the workshop. AWS CLI will get set up after conda, and we're doing LSfR with them.

I'm assuming there will be some steps to do to login to their account and set up 2FA. These should be outlined in the email they will get, but having a reminder here won't hurt.
