[Docs] Fix typo: "feautures" should be "features" in README

## Issue
There is a typo in the README.md under the Tips section.

**Current text:**
> you should also include in your configuration operators
> that can handle those feautures of the data

**Correct text:**
> you should also include in your configuration operators
> that can handle those features of the data

## Fix
Change `feautures` → `features` in README.md

## Steps to Reproduce
1. Open README.md
2. Go to the Tips section
3. See the word "feautures" (misspelled)

This is a minor documentation fix.
