docs: update typo in README.md

[pieter-irsan]

Description

The word "out" doesn't quite make sense in the following text: "Documentation is found at out GitHub Pages site". I suppose it is a typo of the word "our", which makes the sentence like so: "Documentation is found at our GitHub Pages site".
