High-Level Overview

This PR consolidates all sql_ops examples (analysis, dialect, frontend, query) into a single example binary.
Previously, each example had its own file, but now they can be executed via subcommands using:

cargo run --example sql_ops -- [analysis|dialect|frontend|query]

## Which issue does this PR close?

Related to #18142 and
#18743

## Rationale for this change

The catalog examples were moved under
`datafusion-examples/examples/data_io/`, but the doc comments and user
guide
still point to the old paths. This leaves readers with 404s when they
try to follow the examples, so the links need
  to be corrected.

## What changes are included in this PR?

Correct the catalog example links so they point to the examples/data_io
directory.
