Subject: [PATCH] [SPARK-35250][SQL][DOCS] Fix duplicated STOP_AT_DELIMITER to
 SKIP_VALUE at CSV's unescapedQuoteHandling option documentation

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

This is rather a followup of https://github.com/apache/spark/pull/30518 that should be ported back to `branch-3.1` too.
`STOP_AT_DELIMITER` was mistakenly used twice. The duplicated `STOP_AT_DELIMITER` should be `SKIP_VALUE` in the documentation.

### Why are the changes needed?

To correctly document.

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

Yes, it fixes the user-facing documentation.

### How was this patch tested?

I checked them via running linters.

Closes #32423 from HyukjinKwon/SPARK-35250.
