adding additional check for default currency request

This pull request primarily addresses error handling and reporting in the Power Platform API client and related services. The changes involve the addition of a new error code ERROR_ENVIRONMENT_URL_NOT_FOUND, and checks for empty environment URLs in various methods across different services. If an environment URL is found to be empty, the new error is raised with a helpful message. This error is then handled in the Read methods of EnvironmentResource and EnvironmentsDataSource, where a warning is added to the diagnostics only if the error is not ERROR_ENVIRONMENT_URL_NOT_FOUND.

Here are the most important changes:

New error code:

• internal/powerplatform/helpers/error.go: Added a new error code ERROR_ENVIRONMENT_URL_NOT_FOUND.

Error handling in API client and services:

• internal/powerplatform/api/api_client.go: Added extra empty lines for code readability.
• internal/powerplatform/services/authorization/api_user.go, internal/powerplatform/services/data_record/api_data_record.go, internal/powerplatform/services/environment/api_environment.go, internal/powerplatform/services/environment_settings/api_environment_settings.go, and internal/powerplatform/services/solution/api_solution.go: In the GetEnvironmentUrlById method, added a check for empty environmentUrl. If empty, it now returns the new ERROR_ENVIRONMENT_URL_NOT_FOUND error. [1] [2] [3] [4] [5]

Error handling in data sources and resources:

• internal/powerplatform/services/environment/datasource_environments.go and internal/powerplatform/services/environment/resource_environment.go: In the Read method, added a condition to only add a warning to the diagnostics if the error is not ERROR_ENVIRONMENT_URL_NOT_FOUND. [1] [2]

Imports:

• internal/powerplatform/services/environment/datasource_environments.go, internal/powerplatform/services/environment/resource_environment.go, and internal/powerplatform/services/environment_settings/api_environment_settings.go: Added import for helpers to use the new error code. [1] [2] [3]
