GitHub Actions中Codecov上传步骤无法找到令牌的问题排查

我维护的公开GitHub仓库「ncompare」一直使用GitHub Actions及codecov-action，但近期测试工作流中的Codecov上传步骤出现令牌未找到的错误，令牌已以“CODECOV_TOKEN”为名存储为仓库密钥。

错误分为两种形式：
第一种（v4版本action报错）：

debug - 2024-04-09 13:05:05,527 -- Starting create commit process --- {"commit_sha": "dc6df2f3530a6c18f6b23ab63a8549754fae6e1f", "parent_sha": null, "pr": null, "branch": "develop", "slug": "nasa/ncompare", "token": null, "service": "github", "enterprise_url": null}

第二种（v3版本action报错）：

• 切换使用codecov-action的v3和v4版本
• 重新生成并保存新的CODECOV令牌
• 尝试两种参数配置语法：

  with:
    token: ${{ secrets.CODECOV_TOKEN }}
  

  env:
    CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}
