3.82.1
(fix): Send grant_type: "client_credentials" in the OAuth token request when the token
endpoint models grant_type as a plain (non-literal) string. Previously the
generated OAuthAuthProvider omitted grant_type entirely, so token requests
against OpenAPI-imported specs (where grant_type is an optional string rather
than a literal) failed. A required non-literal grant_type is no longer surfaced
as a user-supplied client-credentials option; it is synthesized automatically.
