Codecov always attempts to send a "slack" notification. Slack should be set to "false" in the codecov default config.

Describe the bug

A slack integration is enabled "by default" in the codecov config.

As we can see in the screenshot above the slack_app: true value is in the yaml file. Even though I don't actually have this set in the repo yaml. https://github.com/vlad-ko/laravel-stripe-app-gh/blob/main/codecov.yml

(No "slack" key defined at all).

This causes codecov to attempt to send a notification to slack for every single customer (and every single notification). We also observe this in the support requests when looking at the set of the "attempted notifications", we always seem to try to send a slack notification, even if the customer does not have it configured.
