/**
 * Get all locales for a given environment
 *
 * @param {import("contentful-management/dist/typings/entities/space").Space} space - The Contentful Space object
 * @param {string} sourceEnvironmentId - The ID of the source Environment to create the new environment from - usually 'master'.
 * @param {string} destinationEnvironmentId - The ID of the destination Environment that needs to be created.
 * @param {number} [verbosityLevel=1] - 0 = NONE, 1 = ERROR, 2 = DEBUG, 3 = INFO
 * @returns {Promise<import("contentful-management/dist/typings/entities/environment").Environment|null>} - A Promise that resolves with the duplicated environment object, or `null` if not found.
 *
 * @example
 *
 * // Usage:
 * import contentfulManagement from 'contentful-management'
 * const space = await getSpace(contentfulManagement, 'access-token', 'space-id')
 * const duplicatedEnv = await duplicateEnvironment(space, 'master', 'release-x.y.z', 2);
 * console.log(duplicatedEnv?.sys?.id); // release-x.y.z
