Github Checks / Deploys are failing due to the Twitter Token being excluded in test builds about 11ty-website

Oh, it's because

9:23:19 AM: The following environment variables have been removed from this build to keep them secret:
9:23:19 AM: - OPENCOLLECT_API_KEY
9:23:19 AM: - TWITTER_BEARER_TOKEN

It makes sense but it means we should skip trying to load the twitter feed if it's triggered from a pull request.

Skipping processing the src/follow-feed.11ty.js file in non-privileged builds seems like the least intrusive work-around here.

A more comprehensive option would be setting some compiler flag and accessing it in the source file to determine whether or not to include twitter feeds in the build, depending if the TWITTER_BEARER_TOKEN is present. But that seems more complicated and unreliable, as it would also require a production compiler flag to ensure the twitter feed is attempted in production deployments. Introduce a complexity in a file that shouldn't be involved in building variables.
