Add envs vars for next-build to all tugboat envs

[tjheffner]

User Story or Problem Statement

For CMS preview functionality with next-build on all tugboat environments, certain environment variables need to be present:

OAUTH_PUBLIC_KEY=
OAUTH_PRIVATE_KEY=
DRUPAL_CLIENT_ID=
DRUPAL_CLIENT_SECRET=

These have been added to the CMS PR environment settings here: https://tugboat.vfs.va.gov/5fd3b8ee7b4657022b5722d6/settings/

They are missing from other CMS tugboat environments, namely the CMS MIRROR project that the next-build repo points to.

AP isn't building next-build on BRD environments yet (though we will need to go to staging in a couple sprints for CMS preview), these same values will need to be added there too.

Description or Additional Context

OAUTH_PUBLIC_KEY= https://us-gov-west-1.console.amazonaws-us-gov.com/systems-manager/parameters/cms/staging/drupal_a[…].key/description?region=us-gov-west-1&tab=Table

OAUTH_PRIVATE_KEY=https://us-gov-west-1.console.amazonaws-us-gov.com/systems-manager/parameters/cms/staging/drupal_a[…].key/description?region=us-gov-west-1&tab=Table

DRUPAL_CLIENT_ID= https://us-gov-west-1.console.amazonaws-us-gov.com/systems-manager/parameters/cms/consumers/next-build/client_secret/description?region=us-gov-west-1&tab=Table#list_parameter_filters=Name:Contains:next-build

DRUPAL_CLIENT_SECRET= https://us-gov-west-1.console.amazonaws-us-gov.com/systems-manager/parameters/cms/consumers/next-build/client_id/description?region=us-gov-west-1&tab=Table#list_parameter_filters=Name:Contains:next-build

Steps for Implementation

Add the above environment variables to these (I believe it is these) tugboat settings as well:
https://tugboat.vfs.va.gov/6042eeed6a89945a99399d3d/settings/ < CMS PROD MIRRORS [the environment where next-build repo points to by default is built in this project]
https://tugboat.vfs.va.gov/5ffe2f4dfa1ca136135134f6/settings/ < CMS DEMO ENV
https://tugboat.vfs.va.gov/5fd114f1c65644f68f6376ea/settings/ < CMS-TEST

If it is low-effort to add these variables to the appropriate non-production BRD environments as well, please do so. ❤️

Acceptance Criteria

• Tugboat environments built under any of the cms projects contain the necessary environment variables
