Update half-life-1.md

[bdotsamir]

Half Life 1 is entirely playable, and in fact platinum playable on Crossover. Is reporting crossover compatibility supported on these docs? If not, feel free to close! I'm just not sure where else to put this update 🤷‍♂️

We support crossover, don't get me wrong, but, I think this is unnecessary.

This being up to @IsaacMarovitz obviously but I’d think it would be a good idea to provide this information and use the affiliate url for CrossOver.

Then provide the affiliate url.

I've asked Isaac before about adding redirects to other pieces of software and he's said that we should keep it to Whisky in these docs. That being said, I won't close this as he may feel differently now.

The purpose of the docs should be IMO to provide details on Whisky, and I don't think this is really helpful or in the spirit of the docs.
