[DOCS]: error installing required packages

[Ariugth]

Affected documentation section

requirements.txt

Documentation improvement description

when I am trying to install the required packages I get an error saying "ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'". When I saw the installation tutorial on YouTube, the content of the requirements.txt document is different from the one I downloaded to clone the folder on my computer, I don't know if that is perhaps the reason for the error I get. P.S. I'm new to installing github files.

Why is this change necessary?

to proceed with the installation
