[pyOpenSci review] Add pyright config to pyproject.toml

[rich-iannone]

From the pyOpenSci comment:

(pyrightconfig.json): This is purely a personal preference, but I like having my pyright configuration in my pyproject.toml file. I am not expecting a change, I just wanted to let you know about this possibility.

We plan to circle back to this, and have noted it, but I'm going to close here for now.
