workflows: Update actions to avoid Node.js warning

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

Use updated versions for setup-go[1] and checkout[2] to get rid of the
above warnings.

[2] https://github.com/actions/checkout/releases/tag/v4.0.0
