### What
For newly generated python and low-code connectors, move sources from `src` to `source_%CONN_NAME%` so `airbyte-ci build` can pick them up correctly. Closes#35893.
### What changed?
- Moved the sources from `src`
- Updated package paths in `pyproject.toml` templates
### How to test?
You can make a new connector with `./generate.sh` and verify that it works with Poetry and that it builds with `airbyte-ci build --name source-test`
