[bindings/python] fix project name in txt files.

[gkmngrgn]

Somehow the make command does not work because of the name mismatching. This PR will fix only this issue.

For reproducing the issue:

$ make

Checking requirements files...
mkdir -p .tmp
pip-compile pyproject.toml --quiet             --output-file=.tmp/requirements.txt
pip-compile pyproject.toml --quiet --extra=dev --output-file=.tmp/requirements-dev.txt
diff -u requirements.txt     .tmp/requirements.txt     || (echo "requirements.txt doesn't match pyproject.toml"     && exit 1)

Another issue...

maturin is still not in requirements dev list. Shall we continue to install it manually or add it to dev list?
