[SPARK-34933][DOC][SQL] Remove the description that || and && can be used as logical operators from the document

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

This PR removes the description that `||` and `&&` can be used as logical operators from the migration guide.

### Why are the changes needed?

At the `Compatibility with Apache Hive` section in the migration guide, it describes that `||` and `&&` can be used as logical operators.
But, in fact, they cannot be used as described.
AFAIK, Hive also doesn't support `&&` and `||` as logical operators.

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

No.

### How was this patch tested?

I confirmed that `&&` and `||` cannot be used as logical operators with both Hive's interactive shell and `spark-sql`.
I also built the modified document and confirmed that the modified document doesn't break layout.

Closes #32023 from sarutak/modify-hive-compatibility-doc.
