chore: Rename "Read streams" example to "Streams Pipeline"

[lmammino]

Description

This PR renames the "Read Streams" example in the home page to "Streams Pipeline".

This particular example illustrates how to create a complete streaming pipeline. It's not just reading, but it is also transforming (Gzipping) and writing.

I think "Streams pipeline" is a more appropriate and captivating name for it.
