build: use uv as the package manager in the ci

[mattcristal]

What was done

🧱 Use uv as the package manager to install dependencies. Thus using pyproject.toml and moving away from requirements.txt

Status

⚠️ Experimental, but still asking for a review.

I'd love to move this repo to use a package manager such as uv, however the official guidance from dbt is to use a dev-requirements.txt file with pip to test packages (see dbt-package-testing). I may not agree with this approach but it is what they recommend so until their advice changes I don't think we should implement a package manager.

@pgoslatara thanks for the reply, it makes sense. I have created an issue in the dbt repository to make a suggestion to update to uv - see here
