ci(replay): disable proving job with ethrex_replay until stable (#4410)

**Motivation**

This job is failing consistently: proving with risc0 fails to compile,
and with sp1 the cache is outdated.

**Description**

Remove the CI workflow triggers by temporarily commenting them in
`.github/workflows/main_prover_l1.yaml` until it becomes stable.

I opened issue #4411 to re-enable it.
