Replace deprecated @github/webauthn-json module with native browser methods

[moubctez]

@github/webauthn-json modules has been deprecated. This warning appears when building Core's web components:

 WARN  deprecated @github/[email protected]: Deprecated: Modern browsers support built-in WebAuthn JSON methods. Please use native browser methods instead. For more information, visit https://github.com/github/webauthn-json

The web-site https://github.com/github/webauthn-json explains what to do to switch to native browser methods.

We should check how far that browser support reach and if it's acceptable for us.

@teon Decide if we should cut off support of older then 2025 browsers for this feature to work or we should keep this deprecated lib for those who have older browsers.
