Change column name `storeUrl` to `shopifyStoreDomain`

[sa4mi]

Parent issue: #21

The current column name, storeUrl, does not accurately represent the data stored in the column. To avoid confusion and enhance the clarity of our schema, I recommend changing the column name to storeDomain. This new name will better describe the content of the column and improve overall code readability.

Please note that changing the column name may affect the current hackathon environment. To minimize disruptions, implementing this change last.
