Updating the toolchain versions to fix a bug in 3.13.8. This will make
the release better to everyone.

TODO:
- [ ] Discuss if we should release it together with the 1.7 release, if
  yes, I'll amend the changelog. It contains a bugfix for the 3.13.8, so
  there is value there.

Summary of Changes

Hello @aignas, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the Python toolchain configuration to incorporate the latest available builds for several existing Python versions and introduces support for the new Python 3.15.0a1 alpha release. These changes ensure that the project leverages the most recent bug fixes and features from the Python ecosystem, maintaining an up-to-date development environment.

Highlights

  • Python Version Updates: Several existing Python versions (3.9.24, 3.10.19, 3.11.14, 3.12.12, 3.14.0) have been updated to their latest builds, reflected by changes in their download URLs and SHA256 checksums.
  • Python 3.13.9 Upgrade: Python version 3.13.8 has been upgraded to 3.13.9, with corresponding updates to its download URL and SHA256 checksums across various platforms.
  • New Python 3.15.0a1 Addition: Support for the new Python 3.15.0a1 alpha version has been added to the toolchain, including its specific download URLs and SHA256 checksums for all supported platforms.

Code Review

This pull request updates the Python toolchain versions to use the latest builds, reflected by the change in the build date in the URLs and updated SHA256 hashes. It also introduces support for Python 3.15.0a1 and updates version 3.13.8 to 3.13.9. While the changes are mostly correct, I've found a critical issue where the MINOR_MAPPING for Python 3.13 was not updated to point to the new 3.13.9 version, which could lead to build failures.

Since the BCR release is stuck, I think it's fine to put this in 1.7 and do an rc1

Hi @aignas, I understand you're asking me to adjust the changelog. As an AI, I'm unable to directly modify files or perform actions like updating the changelog. My role is to provide feedback and suggestions.

The summary I provided earlier in this conversation details the Python version updates, including the new Python 3.15.0a1 addition and the upgrade of Python 3.13.8 to 3.13.9. You can use that information as a basis to manually update the CHANGELOG.md file.

If you intended to invoke one of my supported commands, please refer to the /gemini help message for a list of available commands.
