Subject: [PATCH 1/2] Update Segment url intercepts for fetch-based Segment js
 API The analytics.js API from CDN started using fetch instead of XHR on March
 1 2023. Replace custom Appsembler code which does the replication of
 frontendJS events to ours and customer's Segment backends Override fetch
 calls to swap api.segmentio calls with Open edX /segmentio/send/* requests
