### What changes were proposed in this pull request? See title. ### Why are the changes needed? Scala Spark Connect does not adhere to the [documented](https://spark.apache.org/docs/3.5.6/sql-data-sources-load-save-functions.html) behavior. ### Does this PR introduce _any_ user-facing change? As documented in [Generic Load/Save Functions - Spark 3.5.6 Documentation](https://spark.apache.org/docs/3.5.6/sql-data-sources-load-save-functions.html), and similar to Spark Classic and the Python Spark Connect, Scala Spark Connect's `DataFrameReader` should default to the format set via the `spark.sql.sources.default` config. **Currently**: `spark.read.load("..."`) throws ``` java.lang.IllegalArgumentException: The source format must be specified. ``` **Expected**: `spark.read.load("...")` uses the format specified via `spark.sql.sources.default` ### How was this patch tested? Test case added to ClientE2ETestSuite. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
