Update pyproject.toml to use ansys-cookiecutter

[akaszynski]

Given the issue within cookiecutter's release, I've gone ahead and released a renamed, but otherwise identical, ansys-cookiecutter package at https://pypi.org/project/ansys-cookiecutter/.

This is by no means a permanent solution, and since the github repo has 16.5k stars, I'm sure that someone will come up with a workaround, fork, or will just post the package. For now, we're using this to get the job done and will take it down once 2.X is released.

Installation of this package is:

pip install ansys-cookiecutter

and it will show up from pip list as ansys-cookiecutter, but otherwise it's identical to the actual package. For example both:

python -m cookiecutter

python -c "import cookiecutter"

work flawlessly, and otherwise our implementation requires no changes.
