 * The update command modifies documents in a collection. A single update command can contain multiple update
 * statements.
 *
 * @param collectionName The name of the target collection.
 * @param updates An array of one or more update statements to perform in the named collection.
 * @param ordered Optional. If true, then when an update statement fails, return without performing the remaining
 *                update statements. If false, then when an update fails, continue with the remaining update statements,
 *                if any. Defaults to true.
 * @param writeConcern Optional. A document expressing the write concern of the update command. Omit to use the default
