[Bug] ${__interval} in URL parameters is not resolved in public dashboards

[fscherf]

Describe the bug

I use Grafana global variables for timestamps and resolution which works fine but ${__interval} is not resolved on public dashboards. On my REST API, I see Infinity making requests like this:

/time-series-data?from=2025-01-15T0 0%3A00%3A00Z&resolution=%24%7B__interval%7D&to=2025-01-15T23%3A59%3A59.999Z

from and to are resolved correctly, interval is not.

Steps to reproduce

1. Setup a visualization with ${__interval} in a query parameter (screenshot)
2. Share the dashboard via public link
