Fix typos in tips (#14859) There were some typos, grammatical slips, and inconsistent styling in the tips. (Thank you for this project, I am using it right now to teach some new Pythonistas, and happened to notice the "view it's source" typo.)

Fix typos

Enhance `%notebook` to save outputs, including MIME types and exceptions (#14780) ### Description: This PR implements an enhancement to the `%notebook` magic command, enabling it to optionally save the output, including the MIME types and exceptions. ### Changes: Introduced two new dictionaries, `output_mime_bundles` and `exceptions` in history manager, to store output MIME types and exceptions separately. This prevents inflating the history. When the `%notebook` command is invoked, the code extracts MIME types and exceptions from the `history_manager` and appends them to the respective output cells in the generated notebook. ### Feedback Request: Currently, we are using `mime_obj.get_figure()` to retrieve the MIME data for Matplotlib objects. However, this approach only works for the figure object. Are there any other approaches to capture MIME data ? I am using `VerboseTB` to get a structured traceback. While this works for most errors, it doesn't handle syntax errors and some other edge cases very well. In `interactiveshell.py`, different types of errors are handled by using different traceback formats. Should we take the same approach here to handle different types of exceptions? It might result in some repetition, but it could improve error reporting for edge cases.

Patch the `write` method instead to fix downstream tests
