Make Gluten project size small

### Description

It now contains 257MB even if we clone the latest commit
`git clone --depth 1 https://github.com/apache/incubator-gluten.git`

the biggest directories are:
```
27M ./docs/image/gluten_golden_file_upload.png
29M ./gluten-core/src/test/resources/tpch-data
30M ./backends-clickhouse/src/test/resources/tpch-data-bucket/parquet_bucket
40M ./gluten-celeborn/clickhouse/src/test/resources/tpch-data-ch
```

I think we can unify the test data and reduce some unnecessary image size.
