Docs: streamline docs homepage style

[dreamorosi]

What were you searching in the docs?

The homepage of the docs has become a bit crowded and some of the information could be rearranged/restructured.

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/typescript/latest/

How can we improve?

The homepage could be streamlined while made more informative, plus some of the callouts could be removed.

Got a suggestion in mind?
