[Util Change]: Spamming requests when viewing server jars page

### Util Name

Server Jars

### Changes

Use a single endpoint instead of spamming requests per version. Atm you need to goto each individual endpoint to get info such as createdAt causing a long loading time and unnecessary load on the server/user

### Extra Info

Start at the Server Jars page and trace how version data, especially createdAt, is fetched. Compare the current per-version request flow with the requested single-endpoint approach, then verify that the page still shows the same information while making fewer requests.
