Fixes #6300

Description
Describe what problem this is solving, and how it's solved.
.github/workflows/ci.yml uses codecov/codecov-action@v3, which uses a deprecated Node.js version, and this pull request updates it so that it no longer does.

Testing
Explain how this change is tested.
I ran cargo xtask test locally.

Checklist

• Run cargo fmt.
• Run cargo clippy. If applicable, add:
  • --target wasm32-unknown-unknown
  • --target wasm32-unknown-emscripten
• Run cargo xtask test to run tests.
• Add change to CHANGELOG.md. See simple instructions inside file.
