Multiple sentences causes JSON to parse badly for strings files

Sentence breaks in the JSON string values parse badly for translation string files.

The card source here, embedded in a markdown file, will result in two strings extracted string split at "New?" and "Start Here!". This is difficult to manage in Crowdin when applying translations.

Source:

{
    "name": "Prepare",
    "imageUrl": "/static/lessons/firmware.png",
    "description": "To use Microsoft MakeCode with your EV3 Brick, you will need to install the latest LEGO® MINDSTORMS® Education EV3 firmware.",
    "label": "New? Start Here!",
    "labelClass": "red ribbon large",
    "url": "https://makecode.mindstorms.com/troubleshoot"
}
]

This results in two strings for the card in Crowdin:

{
    "name": "Prepare",
    "imageUrl": "/static/lessons/firmware.png",
    "description": "To use Microsoft MakeCode with your EV3 Brick, you will need to install the latest LEGO® MINDSTORMS® Education EV3 firmware.",
    "label": "New?

and

Start Here!",
    "labelClass": "red ribbon large",
    "url": "https://makecode.mindstorms.com/troubleshoot"
}
]
