### Problem
Node.js 20 actions are deprecated. The warning in CI like that:
> Node.js 20 actions are deprecated. The following actions are running
on Node.js 20 and may not work as expected: actions/checkout@v4. Actions
will be forced to run with Node.js 24 by default starting June 2nd,
2026. Please check if updated versions of these actions are available
that support Node.js 24. To opt into Node.js 24 now, set the
FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the
runner or in your workflow file. Once Node.js 24 becomes the default,
you can temporarily opt out by setting
ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see:
https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/
### Changed
Upgrade actions to their latest stable versions:
1. `actions/upload-artifact` v4 => v7
2. `actions/checkout` v4 => v6
3. `actions/checkout` main => v6
4. `actions/create-github-app-token` v1 => v3
5. `github/codeql-action` v3 => v4
6. `actions/cache` v4 => v5
7. `actions/setup-node` v4 => v6
PR https://github.com/redis/redis/pull/14937 updates the Codecov
workflow configuration for `codecov/codecov-action` v6.
The action no longer accepts the singular `file` input, so this switches
to `files` to ensure `./src/redis.info` is uploaded correctly.
This PR introduces Codecov to automate code coverage tracking for our
project's tests.
