Dunky

AWS credentials for S3 write are now obtained from Unity Catalog directly.

FIx bug when providing special characters in ENV var/

Enables reconfiguration of UC Connection

Previously, the connection env variables were required before start of Dunky kernel. This can be tricky if you can only set env variables during the session. Now you can directly update the session env variables inside the Dunky kernel.

For instance:
sql
ENV MYVAR1=MYVALUE1
MYVAR2=MYVALUE2;

Followed by:
sql
RECREATE SECRET;

Update dependencies:
- duckdb >= 1.1

Support auth for creating unity tables
