* refactor(tests): simplify string validation in tests
Introduce a helper function `validate_strings` to streamline the
validation of expected and excluded strings in test cases. Replace
repetitive string assertions in the `test_markitdown_local` function
with calls to this new helper, improving code readability and
maintainability.

- Implemented IpynbConverter class for converting Jupyter Notebook (.ipynb) files into Markdown format.
- Supports markdown cells, code cells and raw cells.
- First markdown heading is used as the title if no title is found in notebook metadata.
- Created a test notebook (`test_notebook.ipynb`) to verify the functionality of the converter.
