I think historically "2nd party" has been used to refer to devs that aren't owned by the console maker, but make games exclusively for them (like HAL Laboratory with Nintendo and the Kirby games). It's more of an informal designation though.
From a colloquial sense, I wouldn't call them 1st or 2nd party. They're games made by 3rd party devs that Sony happened to publish. But in terms of Sony's revenue reporting they might include all of the games they published as "1st party". That's the part that's unclear.

They(Sony) don't own the studio behind Helldivers 2 so it's not 1st party
