analytics: store steam id and timestamp in txt file..

We want some way to track engagement to the site.

We use plausible internally. Already in plausible

We also should log into a txt file w/ UTC timestamp and steamid each time a request to get steam games is made.

No file, test, or entry point is named. Locate the request that retrieves Steam games and determine where the Steam ID is available; then check how UTC timestamps and local text-file logging are handled. Done means each such request records the Steam ID and UTC timestamp in a txt file without breaking the request.
