docs: correct 'event handle' to 'event handler' in Utf8Stream drop event

[rxiddhi]

In this PR, I’ve corrected the incorrect term “event handle” to “event handler” in the Utf8Stream drop event description.
Additionally, I made minor grammatical improvements and ensured consistency in language throughout the section for better readability and technical accuracy.

Hey @rxiddhi!

I noticed that this change also modifies the line wrapping and adds a \ at the end. We try to keep diffs as minimal as possible for easier review and tracking on releases later on.

Would you mind limiting the change to just replacing handle → handler, without altering the formatting? That would be perfect 🙌

For a visual reference:

Hey @UlisesGascon!
Thanks for the feedback! I’ve reverted the formatting changes and kept only the typo fix. Please let me know if anything else is needed.😊
