Literal Tera in Markdown

Zola 0.23.6 templates all Markdown content, including fenced code blocks. Wrap examples that must be displayed rather than executed in a Tera raw block:

{% raw %}
```jinja
{{<project.example value="literal" />}}
```
{% endraw %}

For files that should never execute Tera, add their paths to skip_content_templating in zola.toml. Do not disable templating on pages that use DevLab components.
