Fix "theAdx" capitalization issue

[ian-lr]

A publisher reported an error with the prebid.js package when including a bidder from theAdx. This appears to be a capitalization issue -- the file name itself is theAdxBidAdapter.js but theadx.md has a bidder code of theadx which is then parsed in download.md as theadxBidAdapter.js, leading to a build issue ("error":"Prebid file not built properly").

theAdxBidAdapter.js != theadxBidAdapter.js

This addresses that specific capitalization issue, but perhaps we should modify download.md to downcase all bidder code inputs to avoid case-sensitivity issues.

If the reviewer agrees, I'll try to get a PR that will handle case issues going forward.

Thanks @ian-lr - I'm not a fan of making a generic change here. The Download system is more than a page -- it's a build system running on AWS. I don't want any differences between a standard Prebid.js command-line build and what's done on the Download build server.

Any solution would have to come in the Prebid.js build itself. If that were case insensitive, the general issue would be solved.

Ugh - realized that I got the conflict resolution wrong here -- re-did this fix in #2257

Confirmed it downloads now

@bretg I got you -- that makes sense. I haven't looked into the build system itself yet but let me see if there's an easy fix (at my level of expertise).
