feat: Implement Bookmark Manager

[dklassic]

Implementing bookmark functionality would significantly enhance the user experience in a web browser. Manually entering URLs, even for testing purposes, can become tedious.

We should introduce a Bookmark Manager to facilitate this functionality.

Expected Behavior:

Users should have the ability to view all stored bookmarks and easily navigate to their desired websites with a simple mouse click. Additionally, users should be able to manage their bookmarks by adding or removing entries.

Acceptance Criteria:

• A user interface should be available for users to access and click on bookmarks.
• A user interface should be provided for managing bookmarks, including options to add and delete bookmarks.

Good to Haves:

• The ability to modify existing bookmarks would be a valuable addition.
