docs(contributing): Homogenize format & indent of code blocks

- Format using fenced style.
- Well indent in those placed inside list enumerations.
- Simulate `Good` - `Bad` monospace double colon indent inside each one.

- Examples highlighting as `text-plain`. The `md, markdown` style doesn't work very well since blocks has mixed syntax.
- `check_urls` code block highlighted as `properties` style (key-value pair).

Solves markdownlint rules:
- MD040/fenced-code-language: Fenced code blocks should have a language specified
- MD046/code-block-style: Code block style [Expected: indented; Actual: fenced]

 - 使用 [awesome_bot](https://github.com/dkhamsing/awesome_bot) 進行連結驗證。
 - 可以藉由提交一個內容包含`check_urls=file_to_check`來觸發連結驗證:
 
-```
-check_urls=free-programming-books.md free-programming-books-en.md
-```
+    ```properties
+    check_urls=free-programming-books.md free-programming-books-zh.md

 - 您可以以一個空白區隔出想要進行驗證的檔案名稱來一次驗證多個檔案。
 - 如果您一次驗證多個檔案，自動化測試的結果會是基於最後一個驗證的檔案。您的測試可能會因此通過，因此請詳加確認測試日誌。可以在 pull request 結果中點選"Show all checks" -> "Details" 來查看。
