Inline prop in FormRow has no effect

[haobo-chen]

inline prop in FormRow is dereferenced but not used or passed to any child component

Thanks for the catch 👍

I noted this in a recent change to FormRow (#426):

// Note:  `inline` has no effect at the moment.  In reactstrap 5 and later, this property appears
// to be relevant for the <FormGroup>, though.  As such, we may be able to simplify this class with
// the built-in support of inline forms in newer versions of reactstrap.
