[ci skip] Update what methods `Migration#change` can reverse
* Documentations and comments about what methods
`Migration#change` can reverse is out of date.
For example `change_column_default` is now reversible
by this [commit](https://github.com/rails/rails/pull/20018).
* Comments about `CommandRecorder` dose not match with Rails Guide.
For example `add_foreign_key` is listed only on Rails Guide.
