_getJSONLD doesn't handle https://schema.org/ with trailing /

[danielnixon]

Example: https://www.theparisreview.org/fiction/8364/camouflage-adania-shibli

On that site, Readability fails to extract the author, despite it being in the json-ld:

{
	"@context": "https://schema.org/",
	"@type": "Article",
	"name": "Camouflage",
	"author": {
		"@type": "Person",
		"name": "Adania Shibli, translated by Max Weiss"
	},

The problem is the regex that Readability uses to match against the @context matches https://schema.org but it doesn't match https://schema.org/.

Updating the regex as follows (additional \/?) fixes the issue:

/^https?\:\/\/schema\.org\/?$/

Similar to #933, this one looks like it's already fixed in source and just needs an npm package release.

Closing this in favour of #941
