(fix): Fix WebhooksHelper.VerifyRequest failing to compile on net462/netstandard2.0
(CS1503: cannot convert from 'string' to 'char') when webhook-signature.algorithm-header
uses key-id-parameter/algorithm-parameter: the settings header is now split with
Split(new[] { "," }, StringSplitOptions.None) instead of the Split(string) overload that
only exists on newer target frameworks.
