**Before**

Note that I mostly just moved the contents around except minor changes:
- Removing some questions in FAQ that don't make sense in Apache Spark
- Rename a subtitle "Working with pandas and PySpark" to "From/to pandas and PySpark DataFrames"

For renaming Koalas to either pandas-on-Spark or pandas APIs on Spark, it will be done at SPARK-35591

### Why are the changes needed?

For better readability.

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

Yes, it restructures the documentation as shown above.

### How was this patch tested?

I manually built the docs and tested.

Closes #32820 from HyukjinKwon/SPARK-35647.
