Docs build fails on Hugo v0.128+ due to deprecated resources.ToCSS

[ShivamJha2436]

What steps did you take and what happened:
While building the Contour documentation locally using the latest Hugo (v0.151.1+extended), the build fails with the following error:

ERROR deprecated: resources.ToCSS was deprecated in Hugo v0.128.0 and subsequently removed. Use css.Sass instead.

This error occurs because the docs site still uses the deprecated resources.ToCSS function in its HTML template.

What did you expect to happen:
The documentation site should build successfully with the latest stable version of Hugo.

Anything else you would like to add:
Updating the template to use css.Sass instead of resources.ToCSS resolves the issue.
I’m preparing a PR with the fix and will test it against the current Hugo version to ensure compatibility.

Environment:

• Contour version: v1.33.0
• Kubernetes version: (use kubectl version): N/A
• Kubernetes installer & version: N/A
• Cloud provider or hardware configuration: N/A
• OS (e.g. from /etc/os-release): Arch Linux
• Hugo version: v0.151.1+extended
