"wget: command not found" when executing CurseForge start script.

### Describe the problem

Does the container have wget installed? The modpack I downloaded must use wget to fetch the forge server jar.
Here is the modpack's included ServerStart.sh:
```
#!/usr/bin/env bash
# Start script generated by ServerPackCreator.
# This script checks for the Minecraft and Forge JAR-files, and if they are not found, they are downloaded and installed.
# If everything is in order, the server is started.

Start with the container setup and the CurseForge path that runs /data/FeedTheBeast/ServerStart.sh; inspect how runtime dependencies are installed. Reproduce the shown CURSEFORGE configuration and compare the container's available download tools with the script's wget calls. Done means modpack startup can download the Forge and Minecraft jars without the command-not-found failure.
