Bug: Suspected naming error in `tag` of const `platforms` in `src\serious_python\bin\package_command.dart`

[Creeper19472]

In lines 30-61 of src\serious_python\bin\package_command.dart, the tag key follows a naming pattern such as android-24-arm64-v8a.

This caused problems, at least in Python 3.14.2, for some unknown reason. Pip is unable to find the required package. I'm currently resolving this by adding --platform in pip-related parts of package.dart instead of rewriting it in sitecustomize.py.
