Add Cache Key for Openssl Version Cache / Restore

[aidangarske]

Description

• Fixes version inconsistency error with openssl
• Uses a cache key like wolfssl so we get a clean build every time we invoke a test workkflow

Pull Request Overview

This PR updates the cache key used for the OpenSSL version build cache to include the commit SHA and adds lookup-only restores for a clean, per-commit build.

• Normalize cache key across all workflows to ossl-depends-${{ matrix.openssl_ref }}-${{ github.sha }}
• Introduce lookup-only: true on initial restore and enforce fail-on-cache-miss: true on the subsequent restore
• Applies the change consistently across 14 different GitHub Actions workflows

• Including github.sha in the cache key will generate a unique key per commit, preventing cache hits across workflow runs and defeating the cache benefit. Consider using a stable key based solely on the OpenSSL version (e.g. ${{ matrix.openssl_ref }}) or leverage restore-keys to fall back to previous caches when the key changes.

key: ossl-depends-${{ matrix.openssl_ref }}-${{ github.sha }}

Thanks for the quick fix
