Ees 6048 hotfix revert duckdb dependency version

[duncan-at-hiveit]

This PR:

• fixes the import of CSVs with quote-escaped cells (e.g. "Kingston upon Hull, City of") by reverting to the previously-used version of DuckDB.

The change to the new version of Duck would, without further explicit configuration, result in the following errors when attempting to read form such a CSV:

Message: Invalid Input Error: CSV Error on Line: 34226

This is likely due to a change in DuckDB's default CSV behaviour since version 1.2.0 (we previously used 1.0.2 and the upgrades set the new version to 1.2.1). From the DuckDB v1.2.0 README:

By default, DuckDB now parses CSVs in so-called strict mode (strict_mode = true)

This hotfix will likely be a temporary stopgap. This long term fix will be to:

• Upgrade to the latest DuckDB version.
• Ensure that any reading of CSVs is done with either QUOTE set to " or strict_mode set to false.
• Add tests to handle CSVs with quote-escaped cells in both the initial import of a data set and a "next" import as well.
