Use Node.js 20 for v3

[vkottler]

The v3 action branch triggers the following deprecation warning when used in actions:

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

(example PR)

Is it viable to update v3 to use Node.js 20? The v4 version of this action deletes features compared to v3.

Hi @vkottler - what features in v3 are you missing in v4?

[vkottler]

Per "Breaking Changes" in README.md: Tokenless uploading is unsupported.. This broke my projects' actions and I had to migrate from main to v3.

There doesn't seem to be any compelling reason to set up an API token + store it in a per-repository secret + update action YAMLs so that codecov-action will continue performing the exact same task it previously performed without additional requirements.

Currently v4 is not usable for me in several repos due to #1287.

@felixfontein - we'll take a look at what's going on in #1287

@vkottler Thanks for clarifying. For context, we're not actively supporting v3 beyond critical security fixes.

The primary rationale around upgrading to v4 and having tokens is around reducing service downtime as a result of Codecov's Github app token being rate-limited. The token needs to be generated on the Codecov UI and set as a repo secret.

If you have any questions on setting up the token, let us know, we're happy to help

@vkottler v3.1.5 supports node20. Closing this out for now as we will not be migrating up to node20 for v3 as it is a breaking change for many users.

@thomasrockhu-codecov dope!!! It works great thanks for the suggestion and implementation.
