Update "Drupal as source of truth" documentation

[randimays]

Description

We are in a years-long transition from using VistA as the Electronic Health Records (EHR) system for VA Medical Centers to using Oracle Health (formerly Cerner). As part of the transition, we're moving all data management to Drupal.

Previously, we used a feature flipper called pw_ehr_cta_drupal_source_of_truth to conditionally point this EHR system to VistA or the new Oracle Health system depending on the state of the transition. In January 2023, we removed this flipper and all the logic inside the health care widgets that were using it: https://github.com/department-of-veterans-affairs/vets-website/pull/23018/files. Now all of those widgets are on the Oracle Health EHR system and their data is being managed by Drupal.

We need an update in the documentation to reflect this update. Under the So, how do I use Drupal as the source of truth? header, we have an example linked that demonstrates the flipper behavior, which is now removed.

We need to remove the text in the red rectangle below:

@randimays is removing the info in the red box the only work that needs to be performed for this issue?

[randimays]

@jknipes Yes, this is all that needs to be done.
