fix: misleading help text for 'llama stack build' and 'llama stack run'

current text for 'llama stack build' and 'llama stack run'
says that if no argument is passed to '--image-name' that
the active Conda environment will be used

in reality, the active enviroment is used whether it is
from conda, virtualenv, etc.
