Ensured Secret JWK 'k' byte arrays for HMAC-SHA algorithms can be larger than the identified HS* algorithm. This is allowed per https://datatracker.ietf.org/doc/html/rfc7518#section-3.2: "A key of the same size as the hash output ... or larger MUST be used with this algorithm"
Ensured that, when using the JwkBuilder, Secret JWK 'alg' values would automatically be set to 'HS256', 'HS384', or 'HS512' if the specified Java SecretKey algorithm name equals a JCA standard name (HmacSHA256, HmacSHA384, etc) or JCA standard HMAC-SHA OID.
Updated CHANGELOG.md accordingly.
