When the playground starts. Reth takes 2 slot iterations to sync up at startup. After that, the lighthouse sse stream does not return a consistent stream of event_payload messages every 12 seconds but a mix-up of different slot notifications.
This is not a problem for the rbuilder because it will build blocks anyway but it is not a consistent behavior for the devnet.

## 📝 Summary
This PR does not fix the e2e test but makes it a bit more deterministic
to execute. I feel the problem is that due to
flashbots/builder-playground#14 issue, the
`rbuilder` it not consistent in building blocks at the correct time for
the playground. So, it misses building some blocks.
The previous e2e test would send the transaction to the EL node (to be
picked up by the builder) and the acceptance condition was for the
transaction to be mined and that block to be mined by the local builder.
However, since the builder was not consistent, the transaction would be
mined by the local EL node instead and trigger the acceptance check.
In this fix, I am only sending the transaction to the builder, so that
the EL node cannot include it. Then, if the transaction gets mined, it
was for sure done by the builder. I have tested it locally multiple
times (>10) and it only failed once and I think due to
flashbots/builder-playground#14.
