 - #### Remove Functions bult-in JwtBearer configuration by default
   Azure Functions recently [added configuration](https://github.com/Azure/azure-functions-host/pull/9678) for issuer and audience validation for the default authentication flows, not the one supported by this package through `FunctionAuthorizeAttribute`, which interferes with token validation when using our own Bearer scheme token configuration.
-  In prior versions, this package has functionality to clear Functions built-in configuration, but it was not enabled by default when using `AddJwtBearer(Action<JwtBearerOptions> configure, bool removeBuiltInConfig = false)`. Since the use of this package is commonly used for custom JWT token, the default value of `removeBuiltInConfig` is now `true`.
