fix setup with extra packages specs using '<' or '>'. Always quote

[colonesej]

Description

Allow proper installation of pip or conda packages with < or > specs without bash wrong redirects.

environments:
   myvenv:
      type: venv
      extra_packages: ["setuptools>=77", "wheel", 'numpy==1.*]

now results in something like

pip install 'setuptools>=77' 'wheel' 'numpy==1.*'

previously, the setuptools spec would be passed wrongly to pip

pip install setuptools>=77 wheel numpy==1.*

Just stumbled upon this by chance. You may want to use shlex.quote for something more robust

Thank you for the suggestion @oiffrig , I did not know about that one. Will change the PR

[colonesej]

with shlex.quote it only quotes what is needed, so in the example above the output would be

pip install 'setuptools>=77' wheel 'numpy==1.*'

more robust and neater, thanks Olivier for the hint 👍🏼
