Consider upating GitHub Actions dependencies to latest versions (#751)

Update GitHub Actions dependencies to latest versions

Strongly consider bumping your GitHub Actions to the latest versions.

Your present actions are pinning: 

actions/checkout v4.1.1 (Oct 17, 2023)
actions/setup-go v5.0.0 (unknown, not listed in releases page)
codecov/codecov-action  v4.1.0 (Feb 26, 2024)

These are all positively ancient.

At best you are missing out on new/improved functionality.  At worst you are opening yourself to supply-chain vulnerabilities.
