Bump actions/cache to v4

[hms5232]

v3 is based on Node 16 which be deprecated in action runner, so I switch to actions/checkout@v4.

You can see here (my job) or the following text for detail:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/cache@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.
