* update i18n folder names and keys

* test: add legacy path redirect tests

This uses serve.json from the client-config repo, since we currently use
that in production

* fix: create public dir before moving serve.json

* fix: add missing script

* refactor: collect redirect tests

* test: convert to cy.location for stricter tests

* rename certificate folder to 00-certificates

* change crowdin config to recognise new certificates location

* allow translations to be used

* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

587d7fb9367417b2b2512c12 通過鏈式調用輔助查詢函數來縮小搜索結果 2 301533 chain-search-query-helpers-to-narrow-search-results

--description--

如果不給 Model.find()(或者別的搜索方法)的最後一個參數傳入回調函數, 查詢將不會執行。 可以將查詢條件存儲在變量中供以後使用, 也可以通過鏈式調用這類變量來構建新的查詢字段。 實際的數據庫操作會在最後調用 .exec() 方法時執行。 必須把回調函數傳給最後一個方法。 Mongoose 提供了許多輔助查詢函數, 這裏使用最常見的一種。

--instructions--

修改 queryChain 函數來查詢喜歡 foodToSearch 食物的人。 同時,需要將查詢結果按 name 屬性排序, 查詢結果應限制在兩個 document 內,並隱藏 age 屬性。 請鏈式調用 .find().sort().limit().select(),並在最後調用 .exec() 並將 done(err, data) 回調函數傳入 exec()

--hints--

應該成功地鏈式調用輔助查詢函數。
