[keycloak-user] oidc token_type: "bearer" vs "Bearer"

Hi everyone, While (unsuccessfully) attempting to connect a oidc service provider, I found out that the token_type set by keycloak is "bearer", while my service provider expects "Bearer". Digging the specifications it seems that "Bearer" is the right token_type (see https://openid.net/specs/openid-connect-core-1_0.html#TokenResponse and https://tools.ietf.org/html/rfc6750#section-6.1.1). Should we consider this a keycloak bug? Would a PR fixing this be accepted? Cheers, Christophe
