Make serve - error message about Gemfiles

[bebatut]

What is the issue?

When running make serve or make serve-quick, the commands are not failing but show on the top:

mv: cannot stat 'Gemfile': No such file or directory
mv: cannot stat 'Gemfile.lock': No such file or directory

I am afraid it may be confusing for newcomers.

How to fix that?

This comes from these lines in make serve, make serve-quick

	$(ACTIVATE_ENV) && \
		mv Gemfile Gemfile.backup || true && \
		mv Gemfile.lock Gemfile.lock.backup || true && \

I do not have a good way to fix this

so this only affects conda right? is there any way we could maybe do something like:

install:
  activate_env
  mv gemfile
  gem install ...
  mv gemfile back

because this comes with the big annoyance that people often do a git add -a and end up committing the removal
