Support EdDSA in KeyUtils.keyFactoryAlgorithm()

[Eng-Fouad]

I am trying to decode EdDSA private key using KeyUtils.decodePrivateKey(privateKeyPemEncoded, SignatureAlgorithm.EDDSA). However, the following exception is raised:

java.security.NoSuchAlgorithmException: SRJWT00001: Unsupported key type EDDSA
	at io.smallrye.jwt.util.KeyUtils.keyFactoryAlgorithm(KeyUtils.java:341)
	at io.smallrye.jwt.util.KeyUtils.decodePrivateKey(KeyUtils.java:170)

It seems that KeyUtils.keyFactoryAlgorithm() does not recognize EdDSA.

smallrye-jwt/implementation/common/src/main/java/io/smallrye/jwt/util/KeyUtils.java

Lines 334 to 342 in 6dd836a

	static String keyFactoryAlgorithm(SignatureAlgorithm algo) throws NoSuchAlgorithmException {
	if (algo.name().startsWith("RS") || algo.name().startsWith("PS")) {
	return RSA;
	}
	if (algo.name().startsWith("ES")) {
	return EC;
	}
	throw JWTUtilMessages.msg.unsupportedAlgorithm(algo.name());
	}
