Timeout on Steam product info

[mtkennerly]

Sometime in the last few days, get-steam-app-info.py started timing out on client.get_product_info. I found some related ticketes:

• [BUG] Timeout when requesting get_product_info ValvePython/steam#474
• Always time out when I'm login. ValvePython/steam#472

For now, I've updated the logic so that we ignore the failure: 09b865b. The steam-cache file will still mark those games as needing an update, so the import script can retry them later.

I'll give it some more time to see if it ends up being an issue on Steam's side that gets resolved or if we need to migrate away from the Python library we're using for this. I'd love to switch to a Rust library, but I think I had trouble finding a suitable option the last time I tried.

This seems to have started working again 🎉
