 *

 * import { promises as fs } from 'node:fs'
 * import path from 'node:path'
 *
 * new FileMigrationProvider({
 *   fs,
 *   path,
 *   migrationFolder: 'path/to/migrations/folder'

     * Returns all migrations, old and new.
     *
     * For example if you have your migrations in a folder as separate files,
     * you can implement this method to return all migration in that folder
     * as {@link Migration} objects.
     *
     * Kysely already has a built-in {@link FileMigrationProvider} for node.js
     * that does exactly that.
     *
     * The keys of the returned object are migration names and values are the
     * migrations. The order of the migrations is determined by the alphabetical
     * order of the migration names. The items in the object don't need to be
     * sorted, they are sorted by Kysely.
