Update Segment url intercepts for fetch-based Segment JS API

[bryanlandia]

Change description

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
