Support for DuckDB v1.1.0

Writing to notify that at this moment in time this extension do not successfully build or test against duckdb v1.1.0.

I am writing to inform you that the extension keep being available on duckdb v1.0.0, but can't be distributed on v1.1.0 until the problem is sorted out.

Problem, as detected by the build infrastructure is as follow: https://github.com/duckdb/community-extensions/actions/runs/10619930977/job/29438634772#step:15:4420, and looks to require to adapt to some duckdb-level API changes
