Incorrect command for generating migrations in the documentation

[riyaadh-abrahams]

Hello,

I noticed that the documentation shows an incorrect command for generating migrations. The current command mentioned is:

rails generate neo4j:migration RenameUserNameToFirstName

However, this command does not work. Instead, the correct command should be:

rails generate active_graph:migration RenameUserNameToFirstName

Please update the documentation to reflect the correct command for generating migrations. This will help avoid confusion for users who are following the documentation.

Thanks!
