Implement more fields to be updated from /api/v1/games/{id}

[KairuByte]

Is your feature request related to a problem? Please describe.
The majority of fields related to a game in the database should be overwritable by the admin, be it through the UI or purely through API calls as an advanced feature.

Describe the solution you'd like

When a rawg field is updated by the user, there should be a flag which ignores that field when a cache update takes place. For instance, if the description is updated by the user, it should not be overwritten by a cache update while the website_url, rawg_title and metacritic_rating should continue to be updated.

The following fields should be updatable:

• entity_version
• rawg_id
• title
• version
• release_date
• description
• box_image
• background_image
• website_url
• metacritic_rating
• average_playtime
• early_access
• type
• progresses
• publishers
• developers
• stores
• tags
• genres
