[SPARK-35909][DOCS] Fix broken Python Links in docs/sql-getting-started.md

### What changes were proposed in this pull request?

The hyperlinks in Python code blocks in [Spark SQL Guide - Getting Started](https://spark.apache.org/docs/latest/sql-getting-started.html) currently point to invalid addresses and return 404. This pull request fixes that issue by pointing them to correct links in Python API docs.

### Why are the changes needed?

Error in documentation classifies as a bug and hence needs to be fixed.

### Does this PR introduce _any_ user-facing change?

Yes. This PR fixes documentation error in https://spark.apache.org/docs/latest/sql-getting-started.html

### How was this patch tested?

This patch was locally built after cloning the repo from scratch and then doing a clean build after fixing the required problems.

Closes #33107 from dhruvildave/sql-doc.
