Implement a link to Status Help center on https://status.app/help

Feature Issue

[comment]: # As described in the Status Planning release, the Status Mobile app should include a link to the Status Help support site (https://status.app/help).

User Story

As a user, I want to open the Status Help site from the Status Mobile app so that I can search for the information I need.

Description

[comment]: # Implement a link to the Status Help website at https://status.app/help under the "Help" menu. The label for this link should be "Status Help".
[comment]: # Remove the link to the "Glossary" section. This glossary comes from Status app 1.0 and is no currently maintained by anyone in Status.

Acceptance Criteria

[comment]: # When the user clicks the "Help" option in the Status mobile app, a link to the Status Help website (https://status.app/help) with the "Status Help" text is presented. The user can tap on this link, which opens the Status Help website.
[comment]: # The user doesn't see any link to the Status Glossary.

Notes

[comment]: # Status Help website supports the mobile view.
[comment]: # Status Help documentation content is dynamic and changes several times between releases with new documents and updates to existing documents. For this reason, the Status Help link should open the live https://status.app/help website and not a local copy of the Help website delivered with the binary.
