[python/ci] Unbreak PyPI wheel builds

FileNotFoundError: [Errno 2] No such file or directory: 'requirements_dev.txt'

What happened with 1.9.0 today:

• We only wheel-build on nightlies, or releases
• I tagged a 1.9.0
• I should have tagged a 1.9.0rc0 first 😞
• The requirements_dev.txt PR landed before the nightly wheel-build run could happen

#2311
[sc-43673]

This error was discovered by the workflow python-packaging.yml and not by python-so-copying.yml because the former first builds a source tarball (which doesn't contain requirements_dev.txt) and then builds the wheel from this source tarball, whereas the latter runs python setup.py bdist_wheel directly in the Git repository (where requirements_dev.txt exists)

TileDB-SOMA/.github/workflows/python-packaging.yml

Lines 31 to 33 in 36d5b6e

	- name: Build sdist
	run: python setup.py sdist
	working-directory: ./apis/python

Here is a reprex I ran to reproduce the error locally with Python 3.10 on Linux:

python --version
## Python 3.10.14
uname
## Linux
git checkout 1.9.0
cd apis/python
python setup.py sdist
tar --list -f dist/tiledbsoma-1.9.0.tar.gz | grep requirements

mkdir -p /tmp/soma
cp dist/tiledbsoma-1.9.0.tar.gz /tmp/soma
cd /tmp/soma/
tar -xzf tiledbsoma-1.9.0.tar.gz
cd tiledbsoma-1.9.0/
python -m venv ./venv-soma
conda deactivate
source ./venv-soma/bin/activate
pip install wheel
python setup.py bdist_wheel
## Traceback (most recent call last):
##   File "/tmp/soma/tiledbsoma-1.9.0/setup.py", line 335, in <module>
##     "dev": open("requirements_dev.txt").read(),
## FileNotFoundError: [Errno 2] No such file or directory: 'requirements_dev.txt'

Another bit of debug -- following @jdblischak 's repro, as soon as I do python setup.py sdist then tar --list -f dist/tiledbsoma-1.9.0.tar.gz | grep requirements shows I do have requirements_dev.txt in there

I'm doing this Ubuntu with Python 3.10, clean checkout on release-1.9 branch, all same as @jdblischak ... which is weird ...

I can/will debug since I need to know what's going, but, the good news is we've zeroed in on another of the issues going on
