Arrow IPC integration test "generated_map_non_canonical" failure

**Describe the bug**
There is some problem reading the Arrow Map files from the IPC format

in the reader tests: https://github.com/apache/arrow-rs/blob/81abc1a942cd13a92231f4a828077ad60fdabe36/arrow-integration-testing/tests/ipc_reader.rs#L120-L122

and the writer tests: https://github.com/apache/arrow-rs/blob/81abc1a942cd13a92231f4a828077ad60fdabe36/arrow-integration-testing/tests/ipc_writer.rs#L73-L74

**To Reproduce**
Uncomment one the lines referenced above and the test will fail like the following (looks like the names of the fields are different -- "entries" vs "some_entries")

```

**Expected behavior**

**Additional context**
Found on https://github.com/apache/arrow-rs/pull/3427

Start by uncommenting the referenced cases in arrow-integration-testing/tests/ipc_reader.rs and ipc_writer.rs, then run the failing integration tests. Read arrow-integration-test/src/lib.rs around ArrowJsonField::equals_field and compare the generated_map_non_canonical schema fields. Done means the reader and writer integration tests pass for this Map file.
