duckdb extensions in docker on Apple Silicon

Problem

see duckdb/duckdb#8035

Summary

When using duckdb in a container running on an Mac with ARM processor, it fails to download extensions.

duckdb.duckdb.HTTPException: HTTP Error: Failed to download extension "httpfs" at URL "http://extensions.duckdb.org/v0.9.1/linux_arm64_gcc4/httpfs.duckdb_extension.gz"
> Extension "httpfs" is an existing extension.

Work-around

As suggested in duckdb/duckdb#8035 (comment)

Build duckdb inside the container.

TODO

• try to use another base container
• use a multi-stage build: build duckdb in a builder container
