Errors with http-proxy-agent/https-proxy-agent imports

[LVerneyEC]

Hi,

I had some issues with

engine/src/archivist/fetcher/htmlOnlyFetcher.js

Lines 3 to 4 in aec5133

	import HttpProxyAgent from 'http-proxy-agent';
	import HttpsProxyAgent from 'https-proxy-agent';

and was getting

 - Fetch failed: HttpsProxyAgent is not a constructor

Not sure how widespread an issue this is, but I fixed it by replacing

import HttpProxyAgent from 'http-proxy-agent';
import HttpsProxyAgent from 'https-proxy-agent';

with

import { HttpProxyAgent } from 'http-proxy-agent';
import { HttpsProxyAgent } from 'https-proxy-agent';

Best,
