Golang Client docs: defer cancel(), avoid erroring ...

In the sample code demonstrating how to specify a client request
timeout, the `cancel()` is called immediately after the Put, but it
should be deferred instead, giving the Put enough time to complete.

In the canonical Golang context
[docs](https://pkg.go.dev/context#WithTimeout), the sample code sets a
`defer cancel()` immediately after context creation, and with this
commit we adhere to that convention.

fixes:
