Actual behavior

There seems to be an additional = when a list is passed as a query parameter value on sigil_p:

[test/planner_web/live/projects/show_live_test.exs:124: PlannerWeb.Projects.ShowLiveTest."test GET /projects/:project_id/catalogs button for creating presets exists"/1]
catalog_id #=> "019bd1e2-bb1c-7935-bd3c-a3805e474265"

[test/planner_web/live/projects/show_live_test.exs:128: PlannerWeb.Projects.ShowLiveTest."test GET /projects/:project_id/catalogs button for creating presets exists"/1]
~p"/projects/#{project_id}/product_presets/new?catalog=#{[catalog_id]}" #=> "/projects/016b6f15-a456-61b0-a794-dada3eef117b/product_presets/new?catalog=[]=019bd1e2-bb1c-7935-bd3c-a3805e474265"

Expected behavior

catalog[]=019bd1e2… over catalog=[]=019bd1e2…
