Site Migration: Handle /import/siteSlug.wordpress.com/?flow=onboarding path

[sixhours]

The URL at /import/[siteSlug]/?flow=onboarding points to the import-focused flow. We don't know where the entry points to this URL are.

We may want to redirect this URL to the new site migration flow variant to be safe.

I'm trying to figure out if we have any references to this path that need to be updated. The only reference I've found so far is in the importer controller here:

fbhepr%2Skers%2Spnylcfb%2Spyvrag%2Szl%2Qfvgrf%2Svzcbegre%2Spbagebyyre.wf%3Se%3Q326s4s7p%26zb%3Q2742%26sv%3Q89%2385-og

But that doesn't show where users are coming from.
