Fix broken workflow that deploys to s3

[lxu213]

@veev this automated workflow works and will now push the build files directly to the s3 bucket every time we merge to master if the code compiles correctly!

https://github.com/HopkinsIDD/covid-dashboard-app/blob/master/.github/workflows/s3.yml

Note: the compile has to be clean in order for the workflow to pass (get that green check mark, so we have to be mindful about clearing out unused variables and stuff like that).
