Documentation typo mistake

[bibhatsu]

Hi,
I am installing manim. But there is a small issue in the documentation website:
Its really a small thing, but for beginner it could be a big deal.
https://www.eulertour.com/learn/manim/installation/windows.html

its written
"Install manim python dependencies with pip install -r requirement.txt"
but it should be
"Install manim python dependencies with pip install -r requirements.txt"
Thanks :)
