[Bug]: referral and volume discount programs not appearing in APIs

[cdummett]

Problem encountered

Since #9719 market-sim tests have been failing due to proto changes.

After updating market-sim protos in vegaprotocol/vega-market-sim#524, tests are still failing as the APIs never show the updated programs.

The programs are enacted however as we can see discounts applied to trades.

Observed behaviour

1. Proposal submitted and accepted by core
2. Updated program does not appear in APIs 🔴

Expected behaviour

1. Proposal submitted and accepted by core
2. Updated program does appear in APIs 🟢

Steps to reproduce

1. cd vega-market-sim
1. git checkout gix/governance_protos
1. poetry shell
1. pytest tests/integration/test_trading.py::test_volume_discount_program
