Add Spark 4.0 support

[dolfinus]

Change Summary

• Update CI matrix to include Spark 4.x. By default, it is not used for tests, unless some integration has been changed (like 2.x).
• Spark 4.x also supports Java 22, include it to Readme & CI matrix.
• Update JDBCConnection methods to be compatible with Spark 4.0 JDBCUtils methods signatures.
• Update XML class get_packages() and check_if_supported() methods, as Spark 4.0 includes XML support.
• Since Spark 4.0, DecimalType(38, 10).typeName() started returning decimal(38, 10) instead of decimal, which breaks some Oracle tests. Updated SparkTypeToHWM implementation to have direct mapping between Spark data type classes and HWM classes.

Notes:

• Skip Excel tests on Spark 4.0, as there is no package version.
