Fix parameters for JSONB field

[flvndvd]

Description

While running a relocation in production, we notice some serialization errors:

detail":"Expected \":\", but found \",\".","where":"JSON data, line 1: ..

Indeed, using binds to pass parameters does not work well with array of plain objects. This PR fixes it:

• by ensuring that all paramters are properly sanitized before being saved in GCS
• to temporarily unblock the current workflow, also sanitize in the region if not already done (this will be removed afterward).

Also tested for array of primitives types and regular plain object, those two types don't need any stringify.

Tests

Tested locally, was able to reproduce issue and this fix actually solve the issue.
