Support PEP 735 – Dependency Groups in pyproject.toml

### Issue Kind

Brand new capability

### Description

[PEP 735 – Dependency Groups in pyproject.toml](https://peps.python.org/pep-0735/) just got accepted. This is similar to Poetry's existing depedency groups.

### Impact

It's a new packaging standard that allows for tool agnostic dependency groups.

### Workarounds

Continue using poetry's tool specific dependency groups.
