Demo Notebook Fails on `main` branch: Build-Artifact Mismatch & API Drift

Please describe the bug 🐞

Summary

The example notebook / script shipped with Apache Xtable no longer runs on the current main branch.
Execution fails for three independent reasons:

1. an incorrect JAR coordinate,
2. an outdated method invocation, and
3. the removal of an internal configuration class.

Details

1. Incorrect core-JAR coordinate

<artifactId>xtable-core_${scala.binary.version}</artifactId>

The demo expects a module called xtable-core, but the artifact actually published to Maven Central is xtable-core_${scala.binary.version}.
Because the script loads the wrong coordinate, it cannot find core classes at runtime.

2. Extra argument in HudiConversionSourceProvider.init

hudiConversionSourceProvider.init(
    spark.sparkContext.hadoopConfiguration,
    Collections.emptyMap()   // <-- deprecated
)

init now accepts only a single Configuration parameter.
Passing the second argument produces:

cmd3.sc:19: too many arguments (2) for method init: (x$1: org.apache.hadoop.conf.Configuration)Unit

3. PerTableConfigImpl removed (PR [297] Refactor config classes #480)
   The demo still references PerTableConfigImpl, which was deleted in PR [297] Refactor config classes #480.

cmd3.sc:10: not found: value PerTableConfigImpl

The recommended pattern is to build a ConversionConfig and a list of TargetTable instances instead.

Proposed Fix

• Update the POM line to xtable-core_${scala.binary.version} or the demo scripts.
• Remove the second argument from HudiConversionSourceProvider.init(...).
• Replace PerTableConfigImpl with the new ConversionConfig + TargetTable builder API in the demo.

I can take care of it as well, but let me know either way. Thought this might be a good opportunity for your first contribution.

hi @vinishjail97 I am new to this project, but I still want to study it. Can you give me some help on how to fix and verify this problem? I will develop on Windows and test and verify on Linux.
