🐛 Documentation: smart quotes conversion is applied to diagnostic code blocks

[Nicolapps]

Environment information

Not applicable (bug applies to the biomejs.dev website)

What happened?

On the documentation website, smart quotes substitution is currently applied to diagnostic code blocks. This means that for instance, a " character (U+0022 QUOTATION MARK / ") is displayed as “ (U+201C FT DOUBLE QUOTATION MARK “). Sometimes, the character is also displayed as an HTML entity code (“"” instead of ").

Example from the useGoogleFontPreconnect page:

Expected result

• Access https://biomejs.dev/linter/rules/use-google-font-preconnect/#_top
• The diagnostic code block is formatted as:

  ⚠ The attribute rel=“preconnect” is missing from the Google Font.
  
  > 1 │ <link href=“https://fonts.gstatic.com&quot;/>
      │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    2 │ 

instead of

  ⚠ The attribute rel="preconnect" is missing from the Google Font.
  
  > 1 │ <link href="https://fonts.gstatic.com"/>
      │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    2 │
