[V4] Add missing SkipVersionCheck to TransactWriteConfig

[dscpinheiro]

Fixes #4243

Description

The TransactWriteConfig class introduced in V4 for DynamoDB did not include the SkipVersionCheck option, requiring customers to use the overloads that accept a DynamoDBOperationConfig instead (which have been marked as deprecated).

Testing

Side note but this class is getting out of hand, there's almost 5k lines... Before the test refactoring is done, I'll see if I can clean up this a little bit (for example, by moving the DynamoDBTable classes to their own files).

Pull request overview

This pull request addresses issue #4243 by adding the missing SkipVersionCheck property to the TransactWriteConfig class. Previously, customers had to use deprecated overloads that accept DynamoDBOperationConfig to skip version checks in transactional writes. This change brings TransactWriteConfig into alignment with other configuration classes like SaveConfig, DeleteConfig, and BatchWriteConfig, which already support this property.

Key Changes:

• Added SkipVersionCheck property to TransactWriteConfig class
• Updated the property mapping in ToDynamoDBOperationConfig() method
• Improved error message clarity by removing reference to DynamoDBContextConfig
• Added comprehensive integration test to verify the fix
