Re: [webauthn] User friendly credential ID string for troubleshooting (#2256)

Summary of discussion on 2025-02-26 WG call:

- Some agreement with the need: not uncommon to need some label for "unnamed" credentials but where raw credential ID is too long to comfortably fit in UI. A standardized canonical "short credential ID" consistent between tools would be nice to have.
- Also some skepticism: password managers etc. currently do not display credential ID at all, why would a shorter one be better?
- Why not just fixed-length prefix/suffix of credential ID?
  - Some kind of hash is prudent in case some authenticators emit structured credential IDs with similar prefix/suffixes
- Possible internationalization concerns - user-friendly representation may need to be localizable
