blog: update article pointing to wrong location
Out of date content regarding the location of panic
and recover. Updated to point to correct location inside
encode rather than decode.
Fixes golang/go#30170

-For a real-world example of *panic* and *recover*, see the [[https://golang.org/pkg/encoding/json/][json package]] from the Go standard library. It decodes JSON-encoded data with a set of recursive functions. When malformed JSON is encountered, the parser calls panic to unwind the stack to the top-level function call, which recovers from the panic and returns an appropriate error value (see the 'error' and 'unmarshal' methods of the decodeState type in [[https://golang.org/src/pkg/encoding/json/decode.go][decode.go]]).
+For a real-world example of *panic* and *recover*, see the [[https://golang.org/pkg/encoding/json/][json package]] from the Go standard library. It encodes an interface with a set of recursive functions. If an error occurs when traversing the value, panic is called to unwind the stack to the top-level function call, which recovers from the panic and returns an appropriate error value (see the 'error' and 'marshal' methods of the encodeState type in [[https://golang.org/src/pkg/encoding/json/encode.go][encode.go]]).
The convention in the Go libraries is that even when a package uses panic internally, its external API still presents explicit error return values.
