@homelessbirds hi hi. for some reason the build failed, but i reopened it and it built fine but didn't refresh the deploy preview box

i can see that netlify/docs-website-netlify/deploy-preview "built" from the details link in the GH checks, but i wanted to x2 check that you meant to delete the /es/[...]newrelic.ini files. I'm not familiar with those and they aren't deleted in the EN, JP, KR files... just ES/PT... Are these meant to be deleted when we remove docs from ES/PT directories? (x2 checking because they're related to PHP area of the docs and the lambda docs are part of serverless)
