Option "--extra-index-url" is not recognized

[haiddablitz]

Describe the bug In our dev environment we have a self hosted Gitlab instance and a project with a PyPi repository. After successfully building and pushing a custom Python wheel to that repository we are able to install that wheel via terminal (pip install -r requirements.txt). Trying to install that package via the Requirements plugin is not possible.

To Reproduce Steps to reproduce the behavior:

1. Add --extra-index-url https://__token__:<api-read-token>@<gitlab-url>/api/v4/projects/<project-id>/packages/pypi/simple to requirements.txt
2. Open requirements.txt with PyCharm
3. Try to install the packages via the lightbulb
4. See error (Screenshots)

Expected behavior As other packages the --extra-index-url should be recognized and the package should be installed.
