Subject: [PATCH] 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]
