c1a74637 - refactor path creation in walkTreeWithFlightRouterState (#69383)

refactor path creation in walkTreeWithFlightRouterState (#69383) There's no reason to use `map` here, since it's making the code harder to read and we ultimately have to flatten & filter out falsey values. This updates the path construction to use a `for..of` and only pushes paths that are relevant. This also removes the nested path array that was getting created every iteration of the loop.
