Bee prints version to the stderr

[nugaon]

Summary

I was trying to set the output of the bee version to a variable , when I noticed I don't get anything on the stdout .
I've solved the issue by redirecting the stderr to the stdout, but I don't think it is the intentional behaviour of the command.

Steps to reproduce

BEE_VERSION=$(bee version)
# Empty string
echo $BEE_VERSION
BEE_VERSION=$(bee version 2>&1)
# Actual Bee version
echo $BEE_VERSION

Expected behavior

I can get back the result on the stdout
