chore(legacy-plugin-chart-map-box): bump supercluster to v8

[birkskyum]

SUMMARY

Part of:

• Tracking Issue: Migrating from Mapbox to MapLibre [Approved SIP-130] #30307

Modernizing the legacy-plugin-chart-map-box reduces the diff towards MapLibre.

This PR updates Supercluster from v4 to v8, which improves performance and memory use for of this plugin.

TESTING INSTRUCTIONS

• set the mapbox key in .env
• docker compose up
• open a mapbox chart, and it should still show clusters like below image

@rusackas , how does the review process generally work for these plugins? Are there some specific people who cover this part of the code?

@birkskyum to test/review these PRs, we typically need to check the plugin. There are a few ways to do this:

1. starting an ephemeral env here so anyone can test it (needs to be done by a committer)
2. pulling the change locally and running Superset (better in this case so we can add a mapbox key)
3. pulling the change locally and running Storybook

I'll start with #1 here before I approve. @mistercrunch was your review a code review, or did you test/validate the upgrade?

[mistercrunch]

I only reviewed the 3 lines, seemed benign, didn't test locally

[rusackas]

Tested, works great! Thanks, @birkskyum!

No idea why ephemeral environments aren't working again. Any ideas, @mistercrunch? Did those move to supersetbot or something?
