 * Extracts the DID method from a DID string.

 * If the DID does not follow the expected format, the function returns `undefined`.
 *
 * @param {string} did - The DID string from which the method will be extracted.
 * @returns {string | undefined} The extracted DID method, or `undefined` if the format is not valid.
