Help Center: use Zendesk staging when proxied

[arcangelini]

Related to https://github.com/Automattic/dotcom-forge/issues/9274

Proposed Changes

• Change all configs to use staging zendesk except production.

Why are these changes being made?

To limit the amount of calls made to production Zendesk. Specifically for testing and development.

Testing Instructions

1. Using the live link open /home
2. Open your dev console and watch the network requests.
3. Open Help Center and ensure we are not querying wpcomsupport.zendesk.com at all.
4. Start a chat with Zendesk and ensure all calls are still to the staging environment and the widget that is loaded is green rather than blue.

Could you clarify a bit more the step 4?

Start a chat with Zendesk and ensure all calls are still to the staging environment and the widget that is loaded is green rather than blue.

I tested this in WP-ADMIN and get the production Zendesk when not proxied and the staging environment when proxied.

[arcangelini]

Testing in Calypso I get staging everywhere (local, live link). There is no way to test production other than deploying.

[renancarvalho]

Code wise it is making sense to me, tested the testing steps and all works as described.

LGTM 👍
