fix: canary tests to use a fork (#2739)

Fix #2698 
Fork was always working for `e2e-canary-test` but not for
`run-deployment-canary-uniswap` even though they use the same script and
similar docker-compose file.

BUT the `run_test.sh` script only created the fork variables if
`TEST_NAME = uniswap_trade_on_l1_from_l2.test.ts` - this is true for the
canary test but not the the deployment script where `TEST_NAME =
./src/uniswap_trade_on_l1_from_l2.test.ts`

No point in over-engineering to use the dumped state since
`run-deployment-canary-uniswap` only runs during releases
