fix: code blocks within tabbed content blocks are double spaced

[rafaumeu]

Summary

Fixes #1303

Code blocks within tabbed content blocks were being double-spaced. The root cause was in the tab Hugo shortcode (site/layouts/shortcodes/tab.html), where {{ .Inner | markdownify }} did not trim surrounding whitespace. Hugo's template engine inserts the inner content with leading/trailing newlines, which markdownify then converts into extra <br>/paragraph breaks inside code blocks.

Fix

Changed {{ .Inner | markdownify }} to {{- .Inner | markdownify -}} using Hugo's whitespace trimming delimiters ({{- and -}}), which removes the surrounding newlines before markdown processing.

📝 Walkthrough

Walkthrough

The tab.html shortcode template is updated to use Hugo's whitespace-trimming delimiters ({{- and -}}) when rendering .Inner through markdownify, replacing the previous non-trimming form. This removes surrounding whitespace from the rendered Markdown output.
