Create proper 429 request limit error response

[brennenputh]

The Problem

The error is unclear when this plugin hits a request limit.

Reproduction

Type --John1:1-3 in the editor, and then type a 0 at the end and delete it repeatedly. Eventually, the request will return a HTTP 429 status code, indicating it's hitting a rate limit. This is not shown to the user, however, and simply causes the suggester to stop updating.

Proposed Solution

Return the error in some way to the user - either by a notification popup or by replacing the content in the suggester with something relevant.

a good idea

As a sidenote and addition - when I was looking for the cause of this, I had to replace the fetch in this line with requestUrl to get it to spit out a real error instead of a CORS error. Likely a good change to make, but too small for a PR to fix only that.
