fix: fixed outdated init command (#9422)

* fix: Updating the samples current version of typeorm.

The cli sample was using the getRepository version in the UserController and in the current versions of the typeorm it was deprecated.
Basically I changed the code to the current version using AppDataSource.

* fix: improving code and fixing bugs

I made several changes to the functions because they had bugs, such as the id being a "string" instead of a "number",
the "userRepository" methods being outdated and checking the code to see if the user exists before doing some executions
