Add lookup dependency to url_alias migrations

This was triaged as part of BSI.

It's not clear to me from the title or IS exactly what migrations this is referring to, but I assume it's these ones https://git.drupalcode.org/project/drupal/-/tree/11.x/core/modules/path/...

Neither of those migrations declare any dependencies up front, but they could indeed come from somewhere else.

Setting to PMNMI as we need an IS update and a clearer indication of what needs to happen here.

I don't recall making this issue, and there have been some changes with the addition of the node_complete migration system that may make this trickier, but I'm curious what breaks If we just do what 5-years-ago-me said we should do.

Thanks @mikelutz! That came back green. Not sure how I was reading the old title backwards (read as should not declare dependencies), this makes much more sense!
