Sync ACF Fields on Admin Init

Preview:

/**
 * Synchronizes ACF field groups from JSON files.
 *
 * This function is hooked to the `admin_init` action and is responsible for
 * finding and importing any ACF field groups that have been defined in JSON
 * files but have not yet been imported into the database.
 *
 * The function first retrieves all the field groups defined in the application,
 * and then iterates through them to find any that are defined in JSON format
 * and have not yet been imported. For each of these field groups, it retrieves
 * the local fields and then imports the field group using the `acf_import_field_group`
 * function.
