Update bedrock download URL with custom VERSION

[ncimino]

Using latest docker image with VERSION=LATEST attempts to download:
https://www.minecraft.net/bedrockdedicatedserver/bin-linux/bedrock-server-1.21.51.02.zip

Attempt to manually override with VERSION=1.21.51.01 results in the old URL being used:

2025/01/14 22:49:48	stdout	ERROR failed to download from https://minecraft.azureedge.net/bin-linux/bedrock-server-1.21.51.01.zip

It downloaded the correct version for me:

docker run -it --rm -e EULA=true itzg/minecraft-bedrock-server
DEBU[0000] Using /data to match uid and gid             
DEBU[0000] Resolved UID=0 from match path               
DEBU[0000] Resolved GID=0 from match path               
Looking up latest version...

Perhaps Mojang's site was being cached, which is where the image identifies the latest version to download.

FYI, setting VERSION to 1.21.51.02 is probably what you meant to do for your experiment.
