Title: Adds deprecation notice regarding Callbacks.

Callbacks are being removed in v3. This updates our docs to inform users of the change in three ways:

1. Adds deprecation warnings in the table of contents for these features
2. Adds deprecation warnings at the start of each section for these features
3. Moves these features to the end of the docs
