/**
 * Check if a tag exists in a Contentful environment.
 *
 * @param {import("contentful-management/dist/types/entities/environment").Environment} environment - The Contentful Environment object.
 * @param {string} tagId - The ID of the tag to check.
 * @param {number} [verbosityLevel=1] - 0 = NONE, 1 = ERROR, 2 = DEBUG, 3 = INFO
 * @returns {Promise<boolean>} - A Promise that resolves with `true` if the tag exists, or `false` otherwise.
 *
 * @example
 *
 * Usage:
 * import contentfulManagement from 'contentful-management'
 * const environment = await getEnvironment(contentfulManagement, 'access-token', 'space-id', 'environment-id')
 * const tagId = 'exampleTagId'
 * const exists = await getTagExists(environment, tagId, 2)
 * console.log(exists) // true
