Improve specification return types in starknet_simulateTransaction

[mikiw]

The specification for starknet_simulateTransaction should have a specific trace type like INVOKE_TXN_TRACE, DECLARE_TXN_TRACE, DEPLOY_ACCOUNT_TXN_TRACE instead of using generic TRANSACTION_TRACE that also has L1_HANDLER_TXN_TRACE

https://github.com/starkware-libs/starknet-specs/blob/v0.3.0/api/starknet_trace_api_openrpc.json

It can be achieved by:

• adding a new type that doesn't contain L1_HANDLER_TXN_TRACE
• or instead of using "$ref": "#/components/schemas/TRANSACTION_TRACE" explicitly use these types: INVOKE_TXN_TRACE, DECLARE_TXN_TRACE, DEPLOY_ACCOUNT_TXN_TRACE
