fix: time.NewTicker method panics if argument is less than 0

[lll-lll-lll-lll]

What's Problem

The current implementation in the Client.Run method passes zero to the interval argument of the Wait method https://github.com/replicate/replicate-go/blob/d6f3d9a0308e6b1481784631932d4f7652e7ee36/run.go#L33

This cause panic when initializing time.NewTicker. https://github.com/replicate/replicate-go/blob/d6f3d9a0308e6b1481784631932d4f7652e7ee36/prediction.go#L103

Because time.NewTicker panics when its argument is a value less than or equal to zero.

func NewTicker(d Duration) *Ticker {
    if d <= 0 {
        panic(errors.New("non-positive interval for NewTicker"))
    }

tim.NewTicker()

What I did

• modify comment on the interval arg
• If interval arg is less than 0, returns error
• Changed the arg of the Client.Wait method in the Client.Run method to 1.
