This is fundamentally misunderstanding how capitalism works.
Whoever owns your company pays you as little as possible but as much as necessary, as long as it is profitable. If they don't pay you enough, you leave. If you don't produce enough, they fire you.
There is no "they have enough now, so you get paid more or you can work less".
It is fundamentally adversarial: the whole game is for you to convince them that you are worth as much as possible, and for them to pay you as little as possible. They will lie to you for that, you should be prepared to do the same.
As for the github "contributions". It wasn't ever a good metric (because... metrics), but it has never meant less. With AI, I can generate 10x more commits, and it doesn't mean I produce more value.
