docs: Should the Qdrant intro include / detail examples

[mjang]

The current Qdrant intro as of 23 Nov includes:

they are a compressed version of the data used to train a machine learning
model to accomplish a task like sentiment analysis, speech recognition, object
detection, and many others.

As discussed in PR #400, such examples might not be appropriate for the introduction, at least not without more detail

So the first question is yes/no. Should we include such examples in the intro? Once we answer that question, then we can rewrite the introduction appropriately.

[generall]

The whole sentence

compressed version of the data used to train a machine learning model to accomplish a task like sentiment analysis, speech recognition, object detection, and many others.

looks wrong.

Agree 100%.
