When adding a new key, make it more obvious what the user is entering

[madonius]

When adding a new key the user could receive better guidance from the cli	What the user sees	How this is likely to be interpreted
> fido2luks -i add-key /dev/sda2 <id>	–
Password:	which password?
Password (again):	repeat
\<interaction with the key is expected>	what am I supposed to do here?
Old password:	Is the old password goind to be replaced || The one before was the new password?
Old password (again):	repeat

I think this could lead to frustration on the user's side. Thus I would recommend on the one hand changing the prompts to the passwd phrasing

> $ passwd
Current password:
New password:
Retype new password:

on the other I would propose notifying the user that an action is needed on the security key side.

Thanks for raising that issue, usability is important! I've made some changes #29

fido2luks -i add-key /dev/nvme0n1p1
Current password:
Password to be added:
Password to be added (again):

fido2luks -i replace-key /dev/nvme0n1p1
Current password:
Replacement password:
Replacement password (again):

I prefer to use (again) over Retype... since that avoids having to capitalize the promt which in rust requires more code than it's worth imo.
