Format JSON if jq: filter used on embedded JSON

[RickyRomero]

This fixes an issue where jq: filters will not pretty-print their output if filtering JSON embedded in HTML, for example.

Reproduction steps:

• Add https://careers.nintendo.com/jobs/?department=Design%C2%A0&department=Software+Development%C2%A0&department=Software+Development+-+Games%C2%A0 as a watched URL
• In "Filters & Triggers", add a filter: jq:.props.pageProps.jobs[] | select (.metadata["Job Field"].value == "Design " or .metadata["Job Field"].value == "Software Development " or .metadata["Job Field"].value == "Software Development - Games ") | select (.metadata["Worksite Classification"].value != "Onsite") | {id, title, company_name, worksite: .metadata["Worksite Classification"].value, location: .location.name, updated_at }
• Save the watch.
