feat(meta): handle comma-separated version

This release enables to use coma-separated token for docsearch:version meta tag.

The behaviour of the docsearch:version meta tag will be similar to the meta tag keyword defined from the HTML 5 spec.

The docsearch:version tag can be a set of comma-separated tokens, each of which is a version relevant to the page. These tokens must be compliant with the SemVer specification or only contain alphanumeric characters (e.g.latest, next, etc.). As facet filters, these version tokens are case-insensitive.

For example, all records extracted from a page with the following meta tag:

<meta name="docsearch:version" content="2.0.0-alpha.62,latest">

Will be tagged with the version:

version:["2.0.0-alpha.62" , "latest"]

deps: upgrade Scrapy + Chrome to stable 84

This PR upgrades Scrapy to its latest version (2.2.1). It also removes unnecessary use of CustomContextFactory. It also upgrades the chrome version to its latest stable available v84.

Upgrading Scrapy introduces many benefits such as:

File extensions that LinkExtractor ignores by default now also include 7z, 7zip, apk, bz2, cdr, dmg, ico, iso, tar, tar.gz, webm, and xz
Upgrading Twisted to its lates version. This is required to mitigate with CVE-2020-10109
