Type of change

• Documentation change (change only to the documentation, either a fix or a new content)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Infra/Build change
• Code refactoring

Changes

In the PaddlePaddle implementation of TE, the weights of Linear use a column-major order, whereas paddle.nn.Linear in the PaddlePaddle framework uses a row-major order. This inconsistency in behavior can result in different initialization values between te.Linear and paddle.nn.Linear. This PR addresses and corrects this initialization logic.
