Add game score from Steam

[zclimber]

Problem description

Currently scores are retrieved from PC Gaming Wiki, where Metacritic, IGDB and OpenCritic scores are filled. These scores might not be present for game, more likely for smaller/indie games.

Feature description

So Heroic could also retrieve Steam score (percent of positive reviews) for game.

Additional information

There's an official API to get reviews from Steam - https://partner.steamgames.com/doc/store/getreviews. And similar queries are already made on Linux to check Steam Deck status of game.

For example for this game: https://store.steampowered.com/app/275850/No_Mans_Sky/

You can call this endpoint: https://store.steampowered.com/appreviews/275850?json=1

Which returns this data:

{
    "query_summary": {
        "num_reviews": 20,
        "review_score": 6,
        "review_score_desc": "Mostly Positive",
        "total_positive": 114283,
        "total_negative": 32763,
        "total_reviews": 147046
    },
}
