Note that the Syberia game is technically Syberia: The World Before Prologue. aka the original demo for the game, which was originally released in 2020. The full game came out March 2022, then a new demo in April 2022. STOVE seems to have messed up the naming.
It's just the first two episodes of the game. It may be interesting as a curiosity, as an earlier version of the game and demo. The Prologue used to be available on Steam and GOG, but got pulled in favor of the newer demo.
I found a video playthough of the prologue and the newer demo. Watching a bit of them side-by-side, they're largely the same , although there's some differences in details.
