Remove /hadiths "Get a list of Hadiths" from API docs (#1361)

The following endpoint is listed in the API docs but is not implemented in flask: [/hadiths](https://sunnah.stoplight.io/docs/api/hp9hzrfn7wia9-get-a-list-of-hadiths)

The query parameters specify a collection, book, chapter, and hadith number but the description says that it will return a list of hadiths. This does not make sense because we are specifying a specific hadith number. We already have endpoints that support retrieving a single hadith and also endpoints for returning a paginated list of hadiths in a book.

I also added .venv to gitignore because that is how I am managing my python dependencies.
