new 5bf38031f1 Rename SignatureAlgorithm enum to SignatureScheme
5bf38031f1 is described below
commit 5bf38031f1556bfa9b6a475551394285a095c881

Rename SignatureAlgorithm enum to SignatureScheme
From https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml
Although many use SignatureAlgorithm for this, this one is supposed to
be quite like our Authentication enum (which I am not renaming).
Allow specifying a certificate for ED(25519 and 448) since apparently it
is different from ECDSA, it replaces DSA.
Make MLKEM groups uppercase.
