✨ feat(schemas.py): add BuildStatus enum to represent the status of a build

The BuildStatus enum is added to represent the different statuses that a build can have: SUCCESS, FAILURE, and IN_PROGRESS. This enum will be used to provide a more structured and consistent way of handling build statuses in the application.
