Update integration test and add changelog for debug_traceTransaction error response

Updated DebugTraceTransactionIntegrationTest to expect JsonRpcErrorResponse
instead of success with null for unknown transaction hash. Added changelog
entry covering both debug_traceTransaction (besu-eth#10150) and
debug_traceBlockByNumber (besu-eth#10133) error response changes.

   - Removed `TransactionSelectionResult.BLOCK_OCCUPANCY_ABOVE_THRESHOLD`, in general it could be replaced with `BLOCK_FULL`
 - Experimental Bonsai Archive column families have changed to improve performance during bonsai to archive migration. If you are using the Bonsai archive you will need to do a full resync [#10058](https://github.com/besu-eth/besu/pull/10058/changes)
 - `debug_traceTransaction` and `debug_traceBlockByNumber`: the `error` field in `StructLog` entries is now serialized as a plain string (e.g. `"INVALID_JUMP_DESTINATION"`) instead of an array of strings, aligning with the execution-apis opcode tracer spec. [#10117](https://github.com/besu-eth/besu/pull/10117)
+- `debug_traceTransaction` now returns a JSON-RPC error response (`-32000: Transaction not found`) instead of a success response with `null` result when the transaction hash is unknown [#10150](https://github.com/besu-eth/besu/pull/10150). `debug_traceBlockByNumber` now returns a JSON-RPC error response (`-32000: genesis is not traceable`) instead of a success response with `null` result when tracing the genesis block [#10133](https://github.com/besu-eth/besu/pull/10133).
 
 ### Upcoming Breaking Changes
 - RPC changes to enhance compatibility with other ELs
