openc3.bat needs explicitly --python or --ruby when trying code generator examples, which is undocumented

Hi,

All code examples on the code generator documentation:

openc3.sh cli generate plugin GSE
...
openc3.sh cli generate target GSE
...
openc3.sh cli generate microservice background
...
openc3.sh cli generate limits_response GSE double
...
openc3.sh cli generate limits_response GSE safe
...
openc3.sh cli generate widget HelloworldWidget
...
openc3.sh cli generate widget DataVis

... when using openc3.bat at least, result in:

One of --python or --ruby is required unless OPENC3_LANGUAGE is set.

in .env, by default, OPENC3_LANGUAGE is unset

# This can be used to set the default language for generators
# OPENC3_LANGUAGE=ruby

I assume all above lines should have a proper postfix, or an extra line on top of the instructions should set the variable.
