Max Gekk 7c14f177eb [SPARK-32306][SQL][DOCS] Clarify the result of percentile_approx()
### What changes were proposed in this pull request?
More precise description of the result of the `percentile_approx()` function and its synonym `approx_percentile()`. The proposed sentence clarifies that  the function returns **one of elements** (or array of elements) from the input column.

### Why are the changes needed?
To improve Spark docs and avoid misunderstanding of the function behavior.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
`./dev/scalastyle`

Closes #29835 from MaxGekk/doc-percentile_approx.
