chore: generate github actions workflows (#94)

## What's Changed

Generates GitHub Actions workflows using adbc-gen-workflow from
https://github.com/adbc-drivers/dev. Includes a few other fixes to get
things mostly running:

- Fixes a missing import in go/go.mod that I missed in #31 
- Fixes some imports in go/pkg I missed in #31 
- Adds a basic pixi.toml and empty validation/tests dir

Closes #85
