feat: remove Slack notifications

Slack notifications were not working since 31st of March, due to Slack
moving away from legacy bots.

It's a good opportunity to remove it entirely, as we now relie on
Nutripatrol for moderation, and as it generated many (unread) message.

 Write test cases every time you write a new feature, to test a feature or to understand the working of an existing function. Automated testing really helps to prevent future bugs as we introduce new features or refactor the code.
 
-There are even cases where automated tests are your only chance to test you code. For example: when you write code to post notifications on Slack channel you can only test them  by writing a unit test case.

 There are instances when Robotoff tries to connect to MongoDB via Open Food Facts server. To disable this
 feature (this is disabled by default on local environments), set `ENABLE_MONGODB_ACCESS=0` in your `.env`.
