Enhancement: save variant tabs order

[ashrafchowdury]

Description:

Currently, on the playground page, the position of the variants tabs is changeable but it gets resets to the default tab position after the page is refreshed.

Problem:

Users can reorder the variant tabs on the playground page to suit their workflow. Unfortunately, these customizations are lost whenever the page is refreshed, forcing users to rearrange the tabs each time they visit the page manually.

Proposed Solution:

We can implement a feature that saves the custom order of the variant tabs to local storage. Then when the page is loaded, the application should check for saved tab positions and apply them, allowing users to maintain their preferred tab order across sessions.
