fix: ✨ Add rev key to Images in Parquet

[jeremyarancio]

What

I'm working on the CSV conversion from the Parquet file #19
To compose the image_url's, I need the rev key, which is missing in the Parquet field Images
I also updated the expected Parquet files in Test-Data for the Integration Test => openfoodfacts/test-data#1

Part of

• Generate CSV from parquet files #19
• feat: ⚡ Update Export Parquet tests to consider rev in Images test-data#1
