Typo Update events_listening.md

[defitricks]

Fix typo: "Therefor" → "Therefore"

I found a typo in the following sentence:

• "Therefor, they can communicate changes with the user through events."

The word "Therefor" should be "Therefore".

The corrected sentence is:

• "Therefore, they can communicate changes with the user through events."

"Therefore" is the correct word in this context, as it indicates a conclusion or result. "Therefor" is an incorrect spelling and does not fit the intended meaning. This change ensures the text is clear and grammatically correct.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
