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"]
