Change pip packages to their forked source code in `requirements.txt`

[chankitsaini]

Heroku and Okteto bans anything related to youtube downloading thing. More likely maybe Heroku filter out repositories based on their requirements, same goes for railway. They don't allow youtube pip packages, change:

yt-dlp youtube-search youtube-search-python

to their forked source code, from github and use git+forked_repo_link in requirements.txt. I have tested this bypass, this works perfectly with both railway and Heroku.
