Add New 'Create Lesson' Screen for Simplified Lesson Creation

**Is your feature request related to a problem? Please describe.**
Our application currently lacks a straightforward way for teachers to create new lessons, making the process cumbersome and time-consuming.

**Describe the solution you'd like**
Implement a new 'Create Lesson' screen based on the provided Figma design. This screen should include essential fields like lesson title, description, and content. It should be user-friendly and integrate seamlessly with our existing interface.

**Describe alternatives you've considered**
An alternative would be to modify the existing lesson management section, but a dedicated 'Create Lesson' screen would offer a more focused and efficient user experience.

**Additional context**
The design for this feature is detailed in the following Figma link: [Figma Design](https://www.figma.com/file/uLiqrlxmOB5xCppIzmiUXV/Teacher-Workout?type=design&node-id=1615-3468&mode=design&t=lQ4mebftuOJwV9JG-4). The implementation should be responsive and accessible to all users.
