[Bug] pyproject.toml for pydeck python library needs to have dynamic field #10047
Description
Description
pydeck's pyproject.toml does not declare readme in the dynamic field list, but setuptools attempts to process a readme file as part of the package metadata at build time. Modern setuptools requires that any metadata field populated dynamically (i.e., read from a file rather than statically defined in pyproject.toml) must be explicitly listed under dynamic. Without this declaration, the build fails with an AttributeError.

Expected Behavior
Building pydeck from source should succeed without requiring any patches to pyproject.toml.
Steps to Reproduce
Try building a wheel from the source code:
pip download --no-binary pydeck --no-deps pydeck==0.9.1 && \
tar -xzf pydeck-0.9.1.tar.gz && \
cd pydeck-0.9.1 && \
pip wheel --no-build-isolation --no-deps .
pydeck's pyproject.toml has a minimal [project] table (only name, version, requires-python) while all package metadata — description, readme, license, authors, keywords, classifiers, dependencies, optional-dependencies — is defined in setup.py. Modern setuptools requires that any field defined outside of pyproject.toml be explicitly declared in dynamic; without it, setuptools silently ignores those values.
The fatal error is specifically caused by readme not being listed as dynamic:
AttributeError: 'NoneType' object has no attribute 'get'
Because readme is not declared dynamic, setuptools passes None to its internal _long_description handler instead of the actual value from setup.py, which then crashes when it tries to call .get() on it.
