This endpoint accepts "actions" sent from the "Insights" service.

Once it receives an "action" it'll look through all the achievements that uses it, and will adjust the progress.

If an achievement is completed, it will notify the client through the "Messages" service:

OnAchievementCompleted:
{
	"achievementId": "64085a5a232f5ac280770f79"
}

If the achievement is not completed, but has made progress, it will notify the client through the "Messages" service:

OnAchievementProgress:
{
	"achievementId": "64085a5a232f5ac280770f79"
}

This endpoint should never be called directly, but rather through the configured Pub/sub-topics:

projects/socino-298212/topics/insight-staging
projects/socino-298212/topics/insight-production

The model sent to the pub/sub should look like this:

{
  "key": "letter",
  "gameId": null,
  "playerId": "63d8f5f02849400b10ae0024",
  "value": 1,
  "occurredAt": "2023-03-08T09:50:18.5239534Z",
  "messageId": "uniqueId for this player and action"
}
