[SPARK-51297][DOCS] Fixed the scope of the query option in sql-data-sources-jdbc.md

[llphxd]

What changes were proposed in this pull request?

The documentation shows that the scope of jdbc's option is read/write, but after looking at the source code and testing it, it should actually only be read.
This error has persisted for multiple versions and is still not fixed.

I would love to, but I failed to register jira and have to wait 24 hours. So I'll create the issue later.
