Update Apache-2.0 in pyproject.toml

[dgarros]

I think this should fix the issue in Pypi reported by #975

@dgarros Can you also switch the classifier to:

License :: OSI Approved :: Apache Software License 2.0 (Apache-2.0)

In pyproject.toml

See:

pypa/trove-classifiers#17

FYI, the second part of this didn't work i.e. pypi rejected it:

WARNING  Error during upload. Retry with the --verbose option for more details.                                                     
ERROR    HTTPError: 400 Bad Request from https://upload.pypi.org/legacy/                                                            
         'License :: OSI Approved :: Apache Software License 2.0 (Apache-2.0)' is not a valid classifier. See                       
         https://packaging.python.org/specifications/core-metadata for more information.

Also the classifier never accepted the change that was in the referenced issue (see):

https://github.com/pypa/trove-classifiers/blob/main/src/trove_classifiers/__init__.py#L283

So I am going to revert this part of the PR.

I checked both the METADATA file and the PKG-INFO file and the Properietary License referfence was gone (after reverting the classifier part of this.

So adding the hyphen was sufficient to fix the original issue.

@dbarrosop @ogenstad Should be a quick review/approval.
