feat: enable Figure to be nested within a {{% Markdown shortcode

Browse source 
Based on user request to parse both Markdown and nested HTML shortcodes (Figures) within Callout shortcode: https://discord.com/channels/722225264733716590/742863504515793149/813105748283883570

Uses `{{-` to unindent HTML so that Figure shortcode can be nested within a `{{%` Markdown shortcode, such as Callout, without the HTML being rendered as a Markdown code block. This way we utilise Hugo's HTML in Markdown approach (aka Goldmark `unsafe`) rather than separating HTML from Markdown.

Previously, Figure could only be nested within a `{{<` HTML shortcode.
