chore: bump GitHub Actions to latest major versions

[tomusdrw]

Summary

• actions/upload-pages-artifact v4 → v5 (in deploy.yml)
• actions/github-script v8 → v9 (in visual-regression.yml)

All other actions (checkout@v6, setup-node@v6, configure-pages@v6, deploy-pages@v5, upload-artifact@v7) were already at the latest major.

The github-script@v9 bump is ESM-only; the inline script only uses github.rest.* and context (no require() or getOctokit), so no code changes needed.

Test plan

• deploy.yml runs on next release / manual dispatch
• visual-regression.yml PR-comment step still posts/updates the bot comment on a PR

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
