Python 3.7 has gone EOL. In line with our support policy, we will soon be removing support for new builds targeting this version from the Heroku platform. Existing applications will continue to run.

Drop support for Python 3.7 (#1508)
5c7ccee 
Since:
- It has been end of life upstream since 2023-06-27, so is no longer
  receiving security updates.
- The buildpack has been warning about its end of life in the build log
  output since 2023-02-08 (see #1404, #1460), and its deprecation was
  previously announced on changelog:
  https://devcenter.heroku.com/changelog-items/2530
- The upgrade from Python 3.7 to Python 3.8+ in most cases requires no
  changes to an application at all, or else some small dependency
  updates (compared to say the upgrade from Python 2 to 3).
- Python 3.7 is not compatible with OpenSSL 3, and so only works on the
  Heroku-20 stack - which itself will be deprecated in 2024.
- Any apps that must stay on Python 3.7 short term, can pin to the
  previous buildpack version (`v238`) as a stop-gap.

This also unblocks updating setuptools and pipenv in the buildpack, both
of which have dropped support for Python 3.7 in recent versions.

Closes heroku/roadmap#198.
GUS-W-12345803.
