We should also migrate all existing foreign assets to V4.

When updating the foreign assets from v3 to v4, I get an error in asset_test_utils::test_cases_over_bridge::receive_reserve_asset_deposited_from_different_consensus_works because it requires the runtime to have v3::Location for foreign assets in the version being used.

So in order to do it, the runtimes need to be updated to stable2409 (tested with stable2407 and it didn't cut it) because we need the parachains-runtimes-test-utils crate with version 17.0.0 and right now it's in 15.0.0.

We should move forward with #457

I suggest skipping polkadot sdk stable2407 (#457) and going straight for polkadot sdk stable2409.
