Changed link to last years conference

[jksolbakken]

Fix for #328

Greptile Summary

Updates the previous year conference link logic in the Header component to use conditional domain routing. For years 2026 and earlier, links point to cloudnativebergen.dev, while years after 2026 will use cloudnativedays.no. This addresses the domain migration strategy where historical conferences (2025 and earlier) were hosted on the .dev domain before the organization rebranded to Cloud Native Days.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a simple conditional logic update that correctly handles domain routing for historical conference years. The logic is straightforward, well-contained to a single location, and addresses a specific bug fix (issue Link to last year's conference is broken after domain change. #328) related to linking to previous year's conference.
• No files require special attention
