Add GH action for autorelease on tag #120

Code of Conduct

Description

Adds a github action for publishing release based on tags. Based on this

To create a release, create a tag and push it to GitHub:

git tag -a "v0.0.1-beta" -m "beta version testing"
git push --tags

@rasbt, I think this should be good to go but will need your PyPI API key added to the project secrets.

Pull Request Checklist

• Added a note about the modification or contribution to the ./docs/sources/CHANGELOG.md file (if applicable)
• Added appropriate unit test functions in the ./biopandas/*/tests directories (if applicable)
• Modify documentation in the corresponding Jupyter Notebook under biopandas/docs/sources/ (if applicable)
• Ran PYTHONPATH='.' pytest ./biopandas -sv and make sure that all unit tests pass (for small modifications, it might be sufficient to only run the specific test file, e.g., PYTHONPATH='.' pytest ./biopandas/classifier/tests/test_stacking_cv_classifier.py -sv)
• Checked for style issues by running flake8 ./biopandas
