…t-4.6.2

Bump typescript from 4.5.5 to 4.6.2

The json was generated by rendering the public-gateway-checker locally, and then running the following snippet in the console:

```javascript
console.log(JSON.stringify(Array.from(document.querySelectorAll('.Node')).map((el) => Array.from(el.querySelectorAll('div')).reduce((acc, item) => {

    let content = item.textContent

    if (item.className.includes('Flag')) {
        content = item.style.getPropertyValue('background-image')
    }
    if (item.className.includes('Took')) {
        // Do not serialized the time it took because it may always change
        return acc
    }
    acc[item.className] = content
    return acc
}, {})).sort((a, b) => {
    if (a.Link > b.Link) return 1
    if (a.Link < b.Link) return -1
    return 0
}), null, 2))
```

Also fixed online checks. All gateways show online. Verified manually by clicking each link
