[Doubt] Distribution.get_name() always "UNKNOWN" in extensions when using `pyproject.toml` (in `setuptools.finalize_distribution_options` entry-point)

Description

I've a custom setuptools extension, which tries to do some things, based on the name of the Distribution. It has worked before, but now, we are migrating the keywords from the setup.py to the pyproject.toml and this resulted in the Distribution.get_name() always being UNKNOWN in the Options finalizer (setuptools.finalize_distribution_options entry-point).

Expected behavior

I'd have expected the distribution options to be set when running the option finalizers, regardless of whether the options are set using the pyproject.toml or the setup.py.

How to Reproduce

1. Clone the example from https://github.com/hansingt/setuptools-dist-name-unknown
2. python -m venv venv
3. ./venv/bin/pip install -e .
4. ./venv/bin/python setup.py --name

Output

DIST NAME: UNKNOWN
test

PS: The behaviour is demonstrated using a direct call to setup.py, but it behaves the same, when building the distribution, either using setup.py bdist_wheel,pip wheel, or python -m build. The only difference is, that you don't see the output when running these commands.

Clone the linked setuptools-dist-name-unknown example, create the virtual environment, install it in editable mode, and run python setup.py --name to reproduce the UNKNOWN output. Read the setuptools.finalize_distribution_options entry-point behavior and compare it with the setup.py and pyproject.toml configuration. Done means the distribution name is available to the option finalizer regardless of which configuration file defines it.
