 * Extracts the name of a Map element for sorting purposes.

 * For array expressions (key-value pairs), extracts the first element as the

 * @param params - Parameters object.
 * @param params.sourceCode - The ESLint source code object.
 * @param params.node - The Map element expression to get the name from.
 * @returns The name to use for sorting this Map element.
