docs: Add PyTorch Tensor Operations entry for .logical_xor() (#7787)

[Rishabh1925]

Closes #7787

This Pull Request adds the new documentation entry for the PyTorch tensor method, .logical_xor().

Implementation Details:

• File Path: Created the file at the required location: docs/content/pytorch/concepts/tensor-operations/terms/logical-xor/logical-xor.md.
• Core Concept: The entry defines the Logical XOR (Exclusive OR) operation, explaining that it returns True if exactly one of the elements is non-zero (True).
• Structure: The entry includes the mandatory sections: Description, Syntax, and Example.
• Content: The example clearly demonstrates the Boolean logic using various non-zero and zero values.

Hello @mamtawardhani @codecademy-docs
I have finished creating the new term entry for .logical_xor().

The documentation clearly explains the element-wise XOR operation and its resulting Boolean tensor. Ready for review!

Looks good for a second review! 🚀
