Valid `requirements.yml` file with a git dependency that works via `ansible-galaxy` doesn't work via molecule

[liamjones]

Prerequisites

• This was not already reported in the past (duplicate check)
• It does reproduce it with code from main branch (latest unreleased version)
• I include a minimal example for reproducing the bug
• The bug is not trivial, as for those a direct pull-request is preferred
• Running pip check does not report any conflicts
• I was able to reproduce the issue on a different machine
• The issue is not specific to any driver other than 'default' one

Environment

molecule 25.6.0 using python 3.13
ansible:2.18.6
default:25.6.0 from molecule

and

molecule 25.4.0 using python 3.13
ansible:2.18.2
docker:2.1.0 from molecule_docker requiring collections: community.docker>=3.0.2 ansible.posix>=1.4.0
default:25.4.0 from molecule

What happened

I have a requirements.yml with the following contents:

collections:
  - name: community.general
    source: https://github.com/living-with/community.general
    type: git
    version: hotfix-issue-10305

ansible-galaxy install -r requirements.yml with this file works fine. However, if it's referenced in a molecule test via dependency.options.requirements-file it fails with:

ERROR! Unexpected Exception, this is probably a bug: Non integer values in LooseVersion ('hotfix-issue-10305')

(I just updated the basic test-scenario in the molecule repo to trigger the bug: liamjones@3a367fe)
