Add metadata for Bloom, Weather Station, and ThermoVR games

[LswaN58]

For each game, we need the following information:

• Game name: The title of the game that will appear on the site (i.e. not an internal placeholder name like "Zavala")
• Game description: A 1-2 sentence summary of the game
• Target audience: The grades the game is intended for
• Subject: The closest match for school subject the game is about (e.g. for Wake it is "Life Sciences")
• Play link: Link to play the game
• Source link: Link to the game source code
• "Event Readme" Link: Needs a better name, but a link to the readme or other logging documentation in the game's source code

I'll handle all other items.

To complete:

1. Check out the opengamedata-website repository
   a. Optionally, do this in a codespace instead
2. Switch to the feature/add-new-games branch
3. Open the file at site/data/game_list.json
4. Locate each game, and fill in the items listed above. I've put in placeholder strings ("TODO") for each thing you need to fill in.
5. Commit and push the changes
6. Create a pull request.

I'll handle everything from there.
