Re: [webauthn] Which "pubKeyCredParams" to use? (#1757)

I think I remember being surprised by an ES256 response from Windows 11 at some point, but with Windows 10 and slower-updating (enterprise) installs of Windows 11 still out in the wild, I don't think RS256 is going away any time soon.

But the L3 spec now does suggest a default choice:

https://w3c.github.io/webauthn/#dom-publickeycredentialcreationoptions-pubkeycredparams

This is, admittedly, based on observation of actual algorithms being returned out in the real world (`-7` and `-257`), with a sprinkling of "this is great to use if it's available" (`-8`.) If at some point an algorithm stops being used, or a newer, better algorithm gains traction in the authenticator space, then we should absolutely update this list.
