[Workspace]Add a right sidebar to the workspace create form

[wanglam]

Is your feature request related to a problem? Please describe.

Currently, when creating a new workspace, users have to scroll through the entire form to view form values summary and form action buttons. Additionally, there is no dedicated section or area to display frequently asked questions (FAQs) related to workspace creation. This can lead to the following issues:

1. Users may have to scroll excessively to reference the form values they have entered or to access form actions like saving or canceling.
2. Without a dedicated FAQ section, users may have to search through documentation or seek external help if they have questions or need clarification during the workspace creation process.

Describe the solution you'd like

Implement a sticky right sidebar on the workspace create form that displays:

1. Frequently asked questions (FAQs) related to workspace creation
2. A summary of the form values entered
3. Form action buttons (e.g., Save, Cancel, etc.)
   The right sidebar should remain visible and accessible as the user scrolls through the form, providing quick access to relevant information and actions without the need for excessive scrolling.
