Liang-Chi Hsieh b7bdc3111e [SPARK-28058][DOC] Add a note to doc of mode of CSV for column pruning 
## What changes were proposed in this pull request?

When using `DROPMALFORMED` mode, corrupted records aren't dropped if malformed columns aren't read. This behavior is due to CSV parser column pruning. Current doc of `DROPMALFORMED` doesn't mention the effect of column pruning. Users will be confused by the fact that `DROPMALFORMED` mode doesn't work as expected.

Column pruning also affects other modes. This is a doc improvement to add a note to doc of `mode` to explain it.

## How was this patch tested?

N/A. This is just doc change.

Closes #24894 from viirya/SPARK-28058.
