fix: Remove numbered list formatting from generated tweets issue eliz…

…aOS#16

The Twitter post generator was occasionally adding unnecessary numbered list 
formatting to tweets. This update adds regex patterns to clean the content 
by removing:
- Numbered list markers at the start of lines (e.g. "1. ")
- Trailing numbers and periods at the end of tweets

This results in cleaner, more natural-looking tweets without formatting artifacts.
