The most important changes include adding support for non-Dataverse environments, modifying test workflows, and updating documentation.

Support for Non-Dataverse Environments:

Added support for adding users to environments without Dataverse created. (.changes/unreleased/added-20241118-091212.yaml)
Updated the powerplatform_user resource to handle non-Dataverse environments, specifying that only 'Environment Admin' and 'Environment Maker' roles are allowed in such cases. (docs/resources/user.md) [1] [2]

Workflow Updates:

Modified the test workflow to focus on the TestAccUserResource_Validate_Create_Environment_User test. (.github/workflows/run_tests.yml)

Updated the powerplatform_user documentation to include a note about role compatibility when transitioning from non-Dataverse to Dataverse environments. (docs/resources/user.md)

Example Configuration Adjustments:

Commented out the Azure AD and random provider configurations in example files to reflect the focus on non-Dataverse environments. (examples/resources/powerplatform_user/resource.tf, examples/resources/powerplatform_user/outputs.tf) [1] [2]

Internal Code Refactoring:

Added a new Find function to the array helper to facilitate searching within arrays. (internal/helpers/array/array.go)
