## Changes
Pass additional Azure DevOps system variables required for OIDC
authentication.
* SYSTEM_PLANID
* SYSTEM_COLLECTIONID
* SYSTEM_TEAMPROJECTID
* SYSTEM_OIDCREQUESTURI
	
## Why
These variables are used by the Databricks Go SDK to authenticate with
Azure DevOps OIDC.

Fixes #4226 

## Tests
Added unit test
