pip editable=true doesn't work with multiple requirement names

[dehnert]

Summary

When I pass editable: true and a list of names, I expect each package to be installed as editable. However, Ansible passes just one -e flag to pip, whereas the pip semantics appear to be "the next package listed is editable". This means that only the first package named is installed editable, whereas the Ansible structure (a single editable flag) suggests they all should be.

Steps to Reproduce

Something like this should reproduce:

- name: Install virtualenv
  ansible.builtin.pip:
      name:
          - git+https://foo#egg=foo
          - git+https://bar#egg=bar
      editable: true
      virtualenv: /home/quux/venv

Expected Results

I expect this to run a command like pip3 install -e git+https://foo#egg=foo -e git+https://bar#egg=bar

Actual Results

Instead I get pip3 install -e git+https://foo#egg=foo git+https://bar#egg=bar.

The best workaround is probably something like:

- name: Install virtualenv
  ansible.builtin.pip:
      name:
          - -egit+https://foo#egg=foo
          - -egit+https://bar#egg=bar
      virtualenv: /home/quux/venv

That is, ignore the editable Ansible option entirely and prefix each "package name" with a -e.
