System Test: force timeout when rpc healthy status not within 5 minutes

[sreuland]

What version are you using?

master

What did you do?

build and run system-test from CI workflow - https://github.com/stellar/soroban-tools/actions/runs/6618313640/job/17976470471#step:8:485

What did you expect to see?

tests that pass or fail in timely manner, if the test doesn't get healthy rpc status in 5 minutes, it should force timeout failure instead.

What did you see instead?

hanging test execution that kept running the container, retrying rpc ingestion
