Title: Integrate Custom Sanity Component for Skeleton Theme Selection

Issue:
Currently, our Sanity Studio lacks a user-friendly way to choose a skeleton theme.

Let's enhance the user experience by adding a custom component that allows content creators to select a theme easily.

Changes:

1. Create a custom Sanity component specifically for selecting skeleton themes
   .

2. Integrate this component into the Studio, ensuring a seamless and intuitive user interface.

3. Connect the selected theme to the relevant sections of the project.

Context:
This improvement will empower content creators to personalize the appearance of their content and streamline the process of working with skeleton themes.
