Release v0.2.0

[nfx]

• Added acc and make_acc_group fixtures (#42). In this release, we have added two new fixtures, acc and make_acc_group, to the open-source library. The acc fixture provides a Databricks AccountClient object for use in tests, which can interact with the Databricks account API and automatically determines the account host from the DATABRICKS_HOST environment variable. The make_acc_group fixture is used for managing Databricks account groups, creating them with specified members and roles, and automatically deleting them after the test is complete. This fixture mirrors the behavior of the make_group fixture but interacts with the account client instead of the workspace client. These fixtures enable more comprehensive integration tests for the acc object and its various methods, enhancing the testing and management of Databricks account groups.
