[Feature request] OpenLineage integration produces columnLineage facet without transformations

[dolfinus]

According to OpenLineage spec, columnLineage facet contains transformations field:
https://openlineage.io/docs/spec/facets/dataset-facets/column_lineage_facet/
https://github.com/OpenLineage/OpenLineage/blob/89ac77f816216465e4a8ee2b80e452e4089cc9b4/spec/tests/ColumnLineageDatasetFacet/2.json

For query like this:

insert into def(id,value)
select cde.id, abc.value
from cde
join abc on cde.id = abc.id
where abc.id < 10

It should produce OL event with facet like this:

{
    "columnLineage": {
        "_producer": "https://github.com/trinodb/trino/plugin/trino-openlineage",
        "_schemaURL": "https://openlineage.io/spec/facets/1-2-0/ColumnLineageDatasetFacet.json#/$defs/ColumnLineageDatasetFacet",
        "fields": {
            "id": {
                "inputFields": [
                    {

                        "transformations": [
                            {
                                "type": "DIRECT",
                                "subtype": "IDENTITY",
                                "description": "",
                                "masking": false
                            }
                        ]
                    }
                ]
            },
            "value": {
                "inputFields": [
                    {
                        "namespace": "trino://localhost:8080",
                        "name": "pg.public.abc",
                        "field": "value",
                        "transformations": [
                            {
                                "type": "DIRECT",
                                "subtype": "IDENTITY",
                                "description": "",
                                "masking": false
                            }
                        ]
                    }
                ]
            }
        },
        "dataset": [
            {
                "namespace": "trino://localhost:8080",
                "name": "pg.public.abc",
                "field": "id",
                "transformations": [
                    {
                        "type": "INDIRECT",
                        "subtype": "JOIN",
                        "description": ""
                    },
                    {
                        "type": "INDIRECT",
                        "subtype": "FILTER",
                        "description": ""
                    }
                ]
            },
            {
                "namespace": "trino://localhost:8080",
                "name": "pg.public.cde",
                "field": "id",
                "transformations": [
                    {
                        "type": "INDIRECT",
                        "subtype": "JOIN",
                        "description": ""
                    }
                ]
            }
        ]
    }
}

But instead it produces event like this:

{
    "columnLineage": {
        "_producer": "https://github.com/trinodb/trino/plugin/trino-openlineage",
        "_schemaURL": "https://openlineage.io/spec/facets/1-2-0/ColumnLineageDatasetFacet.json#/$defs/ColumnLineageDatasetFacet",
        "fields": {
            "id": {
                "inputFields": [
                    {
                        "namespace": "trino://localhost:8080",
                        "name": "pg.public.cde",
                        "field": "id"
                    }
                ]
            },
            "value": {
                "inputFields": [
                    {
                        "namespace": "trino://localhost:8080",
                        "name": "pg.public.abc",
                        "field": "value"
                    }
                ]
            }
        },
        "dataset": [
            {
                "namespace": "trino://localhost:8080",
                "name": "pg.public.cde",
                "field": "id"
            },
            {
                "namespace": "trino://localhost:8080",
                "name": "pg.public.abc",
                "field": "id"
            },
            {
                "namespace": "trino://localhost:8080",
                "name": "pg.public.abc",
                "field": "value"
            }
        ]
    }
}

ol_compex_query_start.json
ol_complex_query_complete.json

transformations attribute is missing, and some fields are included to columnLineage.dataset facet although only some of them are a part of INDIRECT column lineage (used in JOIN, WHERE, and not included to final dataset).
