* fix (server): Fix source map retrieval for updated builds

This PR adds the fix submitted in Remix PR #8174. The issue is caused when the build server imports an updated server build with a ?t=timestamp suffix. This causes the source map support library to fail to load the source map.

remix-run/remix#8174

* Update index.js

* fix lint/build issues
