Update Jenkins to also check market-sim for approbation

[gordsport]

As per the changes to be implemented in:

• https://github.com/vegaprotocol/approbation/issues/132

Can we make updates to jenkins to:

1. Add fuzzing ACs as usual
2. Add a new category for fuzzing, not because it's required just for point 3
3. Update the jenkins config for core runs to clone ther vega-market-sim repo
4. Update core's TEST_ARGS to include the market sim test dir (something like '{/workspace/system-tests/tests/**/*.py,/workspace/vega/commands/*.{go,feature},/workspace/vega/core/integration/**/*.{go,feature},/workspace/MultisigControl/test/*.js,/workspace/Vega_Token_V2/test/*.js,/workspace/Staking_Bridge/test/*.js,/workspace/vega-market-sim/vega_sim/scenario/fuzzed_markets/**/*.py}')

Then if the category itself has good coverage and is proving useful, we can look at breaking out fuzzing in the same way that we have done with system tests
