Issue: Error when Retrieving Pages Content of a Notebook Section using Graph Client

Description:
I'm using the Microsoft Graph client to retrieve data from a SharePoint site's OneNote notebook. When attempting to get the content of pages within a notebook's section, I encounter an error. Here’s the relevant portion of my code:

def print_site_notebook_structure():
    client = GraphClient.with_client_secret(
        os.getenv("TENANT_ID"),
        os.getenv("CLIENT_ID"),
        os.getenv("CLIENT_SECRET"),
    )
    site_url = os.getenv("SITE_URL")
    
    # Retrieve all notebooks in a single query
    notebooks = client.sites.get_by_url(site_url).onenote.notebooks.get().execute_query()
    
    # Fetch sections for each notebook
    notebook_sections = {
        notebook: notebook.sections.get().execute_query() for notebook in notebooks
    }
    
    # Attempt to fetch pages for each section
    section_pages = {
        section: section.pages.get_all().execute_query()  # This line causes an error
        for sections in notebook_sections.values()
        for section in sections
    }

    # Print the structure of notebooks, sections, and pages
    for notebook in notebooks:
        print(notebook.display_name)
        for section in notebook_sections[notebook]:
            print(f"    {section.display_name}")
            for page in section_pages[section]:
                print(f"        {page.title}")

Error Encountered:
When calling section.pages.get_all().execute_query(), I receive the following error:

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://graph.microsoft.com/v1.0/sites/{site_id}/onenote/notebooks/{notebook_id}/sections/{section_id}/pages

Investigation & Findings:
After testing and researching the API, I discovered that the correct endpoint for retrieving pages within a section is:

https://graph.microsoft.com/v1.0/sites/{site_id}/onenote/sections/{section_id}/pages

It appears that /notebooks/{notebook_id} should be excluded from the URL path when fetching section pages.

Hope this helps clarify the issue and helps fix the problem.
