Update and fix the testnode

[ImJeremyHe]

This PR:

• Sync with the upstream(not sure if this is necessary for fixing the test node. Fortunately it works and it should be better having the latest version)
• Fix the nitro test node

Key places to review

config.ts

How to test this PR:

In the nitro-integration repo, change the submodule path to this branch (jh/dev-node) and update the submodule

git submodule update --remote nitro-testnode

and

cd nitro-testnode && \
 ./test-node.bash --init --dev --espresso --validate

Run the command above and wait for about 5 mins, if the validator works normally then it is good.
