This adds support for the upcoming Heroku-20 stack. The Heroku-20 Dockerfile is identical to that for Heroku-18, other than the base image, and stack-related env var changes. The initial Python versions made available will be those in: https://devcenter.heroku.com/articles/python-support#supported-runtimes https://devcenter.heroku.com/articles/python-support#supported-pypy-runtimes ...minus CPython 2.7, since it's EOL. Which are: * `python-3.6.12` * `python-3.7.9` * `python-3.8.6` * `python-3.9.0` * `pypy2.7-7.3.2` * `pypy3.6-7.3.2` Note: Unlike CPython 2.7, the PyPy 2.7 branch is still supported: https://doc.pypy.org/en/latest/faq.html#how-long-will-pypy-support-python2 In addition, I've generated binaries for each patch release immediately prior to the latest versions (with the exception of 3.9.0, since there isn't one), otherwise it's not possible to run the "out of date Python" warning tests. The binaries were generated using the process here: https://github.com/heroku/heroku-buildpack-python/blob/main/builds/README.md Specifically: ``` make deploy-runtimes STACKS='heroku-20' \ RUNTIMES='python-3.6.11 python-3.6.12 python-3.7.8 python-3.7.9 python-3.8.5 python-3.8.6 python-3.9.0 pypy2.7-7.3.1 pypy2.7-7.3.2 pypy3.6-7.3.1 pypy3.6-7.3.2' \ ENV_FILE=... ``` Binaries for the GDAL/GEOS/PROJ feature have not been generated, since it's deprecated and due for removal shortly: https://help.heroku.com/D5INLB1A/python-s-build_with_geo_libraries-legacy-feature-is-now-deprecated Note: Like the Python 3.9.0 release, this uses the new S3 bucket, so apps will need to be using a recent version of the buildpack in order to build on Heroku-20: https://devcenter.heroku.com/articles/python-support#checking-the-python-buildpack-version Closes @W-7485877@.
