Add Direct Link for GOG Giveaways

[SobinSiril]

Is your feature request related to a problem? Please describe.

The usual link to the game has to go through 2 or more clicks to get to the actual giveaway.

Describe the solution you'd like

It would be nice if GOG giveaways also had this direct link to the giveaway claim : https://www.gog.com/giveaway/claim

Anything else?

Although not that necessary, this is the direct link to page where you can disable the marketing options that are automatically activated when claiming the free game : https://www.gog.com/account/settings/subscriptions

Sorry for leaving this open for so long. I need to do this while there is currently an offer to determine how to best tackle this. Feel free to ping me again when where's an offer on Gog where the link is not as you would like it to be.

Closing this for now as it's not actionable.
