internal/frontend: add 'Open Source Links' link to deps.dev on unit page

When serving the unit page, make an HTTP request in the background to
deps.dev that checks whether the given module version exists there. If
deps.dev replies in the affirmative within a budget of 250ms, display an
Open Source Insights link alongside the other links in the unit metadata
section.

Add an experiment named "deps-dev-link" to enable this feature.
