DOC: Make writting point thickness consistent

[yvonnefroehlich]

Description of proposed changes

Currently we are using different version to write the thickness of lines. We use

• singluar and plural
• hype and no hypen

e.g., 2-points thick, 2 points thick, 2-point thick, 2 point thick

I think we should decide for one writting and stike to it in the docstrings and examples. So far this PR changes to singular with hypen.
