Add markers to Pipfile when parsing requirements.txt

[geonik-code]

If there are markers specified in requirements.txt they are not currently transferred to Pipfile while generating it. This commit adds markers to Pipfile as defined in requirements.txt

The issue

Using Pipenv with requirements.txt fails when generating Pipfile if there are markers defined in requirements.txt and those markers are for example specifying diffrent os. For example this requirements.txt:
windows-curses==2.3.1 ; sys_platform == 'win32' and python_version == '3.11'
When run under Linux OS with:
pipenv install -r requirements.txt
Throws the following error:

  Hint: try $ pipenv lock --pre if it is a pre-release dependency.

@geonik-code Can you adjust the lint failure and add a news fragment?

[matteius]

Following up on this again -- can the lint issue be addressed so the CI will run?

I am terribly sorry for taking so long to rework it, but I am on it!
