Fix 403 error caused by Github Pages #372
Description
The build is failing on the publishing step to Github Pages:
/usr/bin/git checkout -b github-pages-deploy-action/f5nzqs0et
Switched to a new branch 'github-pages-deploy-action/f5nzqs0et'
/usr/bin/git commit -m Deploying to gh-pages from @ 50ef07f85fc2ed6579d1e86e13ccceeb38bbde3d 🚀 --quiet --no-verify
/usr/bin/git push --force ***github.com/PolicyEngine/policyengine-us-data.git github-pages-deploy-action/f5nzqs0et:gh-pages
remote: Permission to PolicyEngine/policyengine-us-data.git denied to github-actions[bot].
fatal: unable to access 'https://github.com/PolicyEngine/policyengine-us-data.git/': The requested URL returned error: 403
Running post deployment cleanup jobs… 🗑️
/usr/bin/git worktree remove github-pages-deploy-action-temp-deployment-folder --force
Error: The deploy step encountered an error: The process '/usr/bin/git' failed with exit code 128 ❌
Deployment failed! ❌
The task is to review the workflow in code_changes.yaml, understand why this docs step is failing, and fix it. As an added bonus, there are two different Github tokens in here, so please remove any that are not necessary (I think the US_DATA one is not).
