Update Documentation: Clarify paramsSerializer Usage with serialize and encode Fields

[Gn0lee]

Summary

This PR updates the axios documentation to clarify the usage of paramsSerializer. The current documentation is insufficient as it does not explain the new method of assigning an object with serialize and encode fields. This update aims to prevent confusion and ensure proper implementation of custom encoding.

Changes Made

• Added a new section in the documentation explaining how to assign paramsSerializer as an object with serialize and encode fields.
• Provided examples demonstrating the correct usage.
• Highlighted the difference between the previous method of assigning a function directly and the new object assignment method.

Why This Change is Necessary

The recent updates to axios require paramsSerializer to be an object with serialize and encode fields. Without proper documentation, users may face issues where custom encoding cannot be specified, as the function assignment defaults to axios’ basic encoding. This update will help users understand the correct implementation and avoid potential issues.
