Scoru/WASM: extend rollup node tezts to use the WASM PVM

Context

Depends on !5887 (merged).

This MR will contain a tezt end-to-end test that will check that proofs produced by the rollup node are successfully verified by the L1. To do this, we will need to use temporary endpoints to produce dummy proofs. These will be removed once once we have a better mechanism to produce proofs in the rollup node.

Closes: #3412 (closed)
