[OTel Demo] - Quote Service Metrics

[julianocosta89]

This OTel Demo PR added metrics to the PHP service.
We need to add the process to the docs.

@open-telemetry/demo-approvers @open-telemetry/php-approvers is this still relevant?

[julianocosta89]

Yes, we need to update this section: https://opentelemetry.io/docs/demo/services/quote/#metrics

I can take care of this

@kennykguo feel free to take it, I've actually forgot to update it.
I was wrapping my head around it, as there is not much on metrics in the quoteservice other than those lines:
https://github.com/open-telemetry/opentelemetry-demo/blob/main/src/quoteservice/public/index.php#L64-L68

I'm not sure how we could add that in the docs, but I'm open to suggestions.

@brettmc do you think we have something to add to the Metrics section of the PHP service in the docs?

Otherwise I'll just close this issue
