Fix Generate Contributors PNG workflow: convert script to ESM

[Vaivaswat2244]

Changes

The Generate Contributors PNG workflow fails on every run with ReferenceError: require is not defined in ES module scope. utils/contributors-png.js is CommonJS, but package.json has "type": "module", so Node resolves it as ESM. It fails on every Node version — the script was added a month after the repo switched to ESM and has never worked, which is why contributors.png has only ever been updated by hand.

• Renamed utils/contributors-png.js → utils/contributors-png.mjs and converted it to ESM (import instead of require, top-level await instead of the async IIFE). Matches utils/, where every other script is already .mjs.
• Updated the run: step in .github/workflows/contributors-png.yml.

No behaviour change beyond the module format.

The workflow can't run on a PR (on: push filtered to .all-contributorsrc, gated on refs/heads/main), so tested on a fork: . This is a stopgap — the script is meant to be replaced by processing/all-contributors-image#4.

@Vaivaswat2244 thank you for spotting this one, good work!

traced this back to the branch switch(#8871), when 2.x became main. the workflow had previously been running against the v1 branch, where contributors-png.js was treated as cjs. on the new main, package.json has "type": "module", so node treats the .js generator as esm and require() fails.

tldr; the script worked fine before the default branch switched to v2.

also tested the fix locally, @ksen0 we can merge this one!

Thanks for the confirmation @skyash-dev . Though this is still a stopgap and this should be perma fixed with processing/all-contributors-image#4

I have left some reviews there, which should help the pr converge to approval soon. Thanks again
