Frontend - vendorlist warning

[arelra]

As reported by @sndrs

When running make compile in Frontend the following error/warning is reported:

Body from GETting 'https://vendorlist.consensu.org/vendorlist.json' is not valid JSON

Falling back to [redacted]/code/frontend/static/vendor/data/cmp_fallback_vendorlist.json

This is code from download.mjs

The static/src/javascripts/projects/commercial/modules/cmp directory from the PR that added this code also no longer exists

It looks like this is old code related to cmp vendorlists that can be deleted.
