Support JSON in script tags

[ascorbic]

There are a number of cases where script tags containing JSON are used. These include the new import map spec and JSON-LD microformat blocks. Can I request that the following script types are interpreted as JSON:

• application/json
• importmap
• application/anything+json
• anything-importmap

Anyone working on this? Importmaps hitting all browsers means this would be a nice feature to have. I tried digging into the regexes, but it's not as simple as adding type="importmap" to the existing script tags, as this needs to to be JSON highlighted, not JS highlighted
