pip cache always uses node process architecture, ignoring architecture key

Description:

The pip caching code uses a cache key that does not include the Python binary's architecture. This leads to cache thrashing.

https://github.com/actions/setup-python/blob/main/src/cache-distributions/pip-cache.ts#L68-L75

These keys should include the Python binary architecture, which is specified with the architecture input to the action.

Action version:
5.2.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
All

从 src/cache-distributions/pip-cache.ts 第 68-75 行开始，检查 pip 缓存键是如何组装的，以及 action 的架构输入如何可用。更新相关缓存键，使其包含 Python 二进制文件的架构，然后验证不同架构不再复用同一个缓存键或争用同一个缓存键。
