Website: Broken Link to memcached_controller.go example on quickstart

[RiRa12621]

Bug Report

What did you do?
Accessed https://sdk.operatorframework.io/docs/golang/quickstart/ and clicked the link to the memcached_controller.go example

What did you expect to see?
The memcached_controller.go example located at https://github.com/operator-framework/operator-sdk/blob/master/example/memcached-operator/memcached_controller.go.tmpl

What did you see instead? Under which circumstances?
a 404 page from github because the website points to https://github.com/operator-framework/operator-sdk/blob/master/example/kb-memcached-operator/memcached_controller.go.tmpl

Possible Solution
The latest version of the website includes the right link https://github.com/operator-framework/operator-sdk/blob/master/website/content/en/docs/building-operators/golang/quickstart.md

This has been fixed in the v0.19.x branch:
https://v0-19-x.sdk.operatorframework.io/docs/golang/quickstart/#implement-the-controller

We've made the decision to keep the latest branch (which is what is published at sdk.operatorframework.io) aligned with the git tag for the latest release, so those changes won't show up on the main site until we cut another release.

It also is fixed in the master: https://master.sdk.operatorframework.io/docs/building-operators/golang/quickstart/. And s @asmacdo said it will be available in the latest one after the next release with docs (probably 1.0.0).

Also, I'd like to recommend you follow up the migration steps by checking the preview of the PR #3543 which we are working and has many fixes and updates.

I am closing it a sorted out since it is fixed in the master.
