Express.js example missing

[ghost]

The examples README.md points to a non-existing express.js example: https://github.com/open-telemetry/opentelemetry-js/blame/main/examples/README.md#L19

Considering that Express.js is the most widely used Node.js web application framework, I feel like that example should definitely be present.

Cheers :)

It was moved to the contrib repo https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/examples/express

The examples readme should be updated to remove it and to point to the contrib repo for additional examples.
