docs: An example of using Writer to create a missing topic imports has an import error in README

[VMois]

Describe the bug

An example of creating a missing topic using Writer in README (link) is using this snippet to check for retriable errors:

if errors.Is(err, LeaderNotAvailable) || errors.Is(err, context.DeadlineExceeded) {
        time.Sleep(time.Millisecond * 250)
        continue
}

Go complains that LeaderNotAvailable is not found. You need to change the line to kafka.LeaderNotAvailable for it to work. An example from my learning project here.

If it is okay, I would like to open PR with a fix. Thank you.
