Issue:
bug: Error when using Hugo 0.147.3+: 'no such template "_default/_markup/td-render-heading.html"'
*Description*:
When using newer versions of Hugo (0.147.3+) with the Envoy Gateway documentation site, template generation fails due to a missing template file. This affects both building the site and creating new documentation using archetypes.

*Repro steps*:
1. Upgrade Hugo versions (0.147.3+) 
2. Try to use create a doc template
`hugo new --kind task content/en/latest/tasks/your-category/your-new-task.md`

You will see the following error:
`html/template:_markup/render-heading.html:1:12: no such template "_default/_markup/td-render-heading.html"`
