Issue describing the changes in this PR

resolves #1805

Removing WorkerExtensionBinding sample and updating the Extension sample project.

Future work: Updated best practice for output without using the output binding

@liliankasem just an FYI we were using some of these code examples in our documentation. The hint is that for most of these I added snippet tags to the source code. This caused a break in our Azure documentation build until they removed the snippets from the source .md files.

Adding @mattchenderson for awareness.

😱 oh no! I didn't realise, thanks for the info - will keep this in mind with future updates. Is there anything we can do to help update the docs?
