Preserve ToC State Across Section Navigation

[martyanovandrey]

The current side navigation (ToC) in the documentation closes all other sections when a user navigates to a specific section, leaving only the selected one open. We need to enhance the ToC component to ensure that the state is preserved, allowing all previously opened sections to remain open when a user navigates to a section.

Task:

• Update the ToC component to maintain the open/close state of sections across navigation.
• Ensure that multiple sections can be open simultaneously after navigation.
• Test the updated functionality to confirm state persistence.
