Bump Node version to 20

[lenvm]

What

This PR updates the actions using Node 16 to Node 20

Why

GitHub is deprecating Node 16 for GitHub Actions. Therefore currently workflow runs using this action show the warning Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: arduino/setup-arduino-cli@v1. This PR implements that change.

More information is found on GitHub Actions: Transitioning from Node 16 to Node 20

I hope this can be merged, as GitHub has announced that it will stop supporting Node16 "by Spring 2024".

It is not entirely orthodox to review the changes myself, but there seems to be a lack of will, and the truth is that they are quite simple.

@latchdevel thank you for the ping. Sorry for the late response, I will prepare a followup PR to address some changes made in arduino-cli tagging convention, so this action will be able to pickup new v1.y.z versions.
