Cross-OS Version Cache Pollution

[Kurt-von-Laven]

Description:
A cache saved on one version of a given OS can be restored on a different version of that OS. Package managers and individual packages typically assume the OS version wasn't swapped out from under them, so this can produce a wide variety of issues. See actions/cache#543 for evidence that this is a real problem with GitHub Actions in general and the officially recommended solution.

Action version:
v4.5.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
All

Repro steps:

1. Save a cache on ubuntu-20.04, for example.
2. Attempt to restore the cache on ubuntu-22.04.

Expected behavior:
The cache misses and is saved again.

Actual behavior:
The cache hits and is restored.
