CI fix: add retries to eth1 sim tests (#4501)

## Issue Addressed

This PR attempts to workaround the recent frequent eth1 simulator failures caused by missing eth logs from Anvil. 

> FailedToInsertDeposit(NonConsecutive { log_index: 1, expected: 0 })

This usually occurs at the beginning of the tests, and it guarantees a timeout after a few hours if this log shows up, and this is currently causing our CIs to fail quite frequently. 

Example failure here: https://github.com/sigp/lighthouse/actions/runs/5525760195/jobs/10079736914

## Proposed Changes

The quick fix applied here adds a timeout to node startup and restarts the node again.

- Add a 60 seconds timeout to beacon node startup in eth1 simulator tests. It takes ~10 seconds on my machine, but could take longer on CI runners.
- Wrap the startup code in a retry function, that allows for 3 retries before returning an error.

## Additional Info

We should probably raise an issue under the Anvil GitHub repo there so this can be further investigated.
