Enable pre-sales chat for logged-in users in Production env.

[elliottprogrammer]

Proposed Changes

This PR enables the Zendesk pre-sales chat for logged-in users on the Jetpack Cloud pricing page.

Additional context: We implemented a Zendesk pre-sales chat interface ( #70590 ) that would only display for logged-out users, however now we want to increase the chat volume by enabling the chat interface to logged-in users also.

Implementation notes:

Enabled feature-flag: jetpack/zendesk-chat-for-logged-in-users in production env (in file: jetpack-cloud-production.json).

Related to #71253

Testing Instructions

Just simply review the code. Verify that in the file config/jetpack-cloud-production.json the feature property jetpack/zendesk-chat-for-logged-in-users is set to true.

I don't think there is any other"manual" way to test this PR, other than to just manually inspect the code. And then once deployed, we can then test that the chat is showing for logged-in users. 🤷‍♂️
