twitch: Sync scopes with the latest API specs

[vpetrigo]

Sync Twitch API scopes according to the latest specification available here.

I used the following code to generate variable-scope code. It may be helpful for further syncs. 😅

let scopeNames = Array.from(document.getElementsByClassName(
    'highlighter-rouge')).filter(element => element.innerText
    .match(/^[a-z:]+$/));

for (let i of scopeNames) {
    let elementText = i.innerText;
    let capitalizedScopeName =
        `Scope${elementText.split(/[:_]/).map((element) => element.charAt(0).toUpperCase() + element.slice(1)).join('')}`;
    console.log(`${capitalizedScopeName} = "${elementText}"`);
}
