Refactor weekly update script to run as a `github-script` action

[dhruvkb]

Description

The weekly update script last_week_tonight.mjs runs as a standalone Node.js script. It is the last remaining standalone script in the JS based automations. Converting it to a actions/github-script based job would bring the following improvements:

• consistency with other jobs like issue and PR automations
• uniformity of code structure and documentation
• identical guides for testing these scripts locally
• possibility to unit test all workflow jobs using common patterns #1916
• ability to convert @octokit/rest to a dev-dependency

This is closely related to #3445 as they both deal with improvements to the same workflow.

Is .github/workflows/weekly_updates.yml not already running a github action based job?

[dhruvkb]

It's currently invoked as a Node.js script. This means that to run this, we first need to set up up Node.js, install dependencies and then finally invoke the script using a run step.

https://github.com/WordPress/openverse/blob/b004dc620897d832fefa01c97a4fe16206adc713/.github/workflows/weekly_updates.yml#L28-L29

We want to update the script so that we can invoke it from actions/github-script. This generally involves

• moving top-level code into a main() function
• replacing custom Octokit with the github argument
• accepting a core argument and then using core.info(), core.warn() and core.error() for logging

For an example, see the issue_automations.yml workflow. It does not need a setup step and we get access to an authenticated Octokit instance (octokit) and the GitHub actions toolkit (core) for free.

You can also refer to the actual script automations/js/src/project_automation/issues.mjs that contains the aforementioned main() function.
