Update infinite-scrolling.mdx (#117)

I was a little confused by the wording and meaning of the first sentence, so I moved the word "that" so that it would make more sense to me. But please make sure that it's correct. I figure there was a typo and wasn't sure what you had wanted it to say, so I just took my best guess.

Also, I noticed that in other places, you referred to the virtualization feature as a singular feature, so I changed it to singular here, but feel free to change it back to what you had before.

 ## Infinite Scrolling Example
 
-An infinite scrolling table that is a table streams data from a remote server as the user scrolls down the table. This works great with large datasets, just like our [Virtualized Example](/docs/examples/virtualized), except here we do not fetch all of the data at once upfront. Instead, we just fetch data a little bit at a time, as it becomes necessary.

 Using a library like [`@tanstack/react-query`](https://tanstack.com/query/v4) makes it easy to implement an infinite scrolling table in Material React Table with the `useInfiniteQuery` hook.
 
-Enabling the virtualization features here are actually optional, but encouraged if the table will be expected to render more than 100 rows at a time.
