Update documentation for create migration command

[maxmarkus]

Hello 👋

Thank you for this really nice pieces of software, perfectly suited for my side project.

Wasn't able to find the documentation repo, so I put it here.

Here https://squareboat.com/open-source/nestjs-boilerplate/database/migrations
On the "Create new migration" the command should be node cli make:migration create_users_table, since the command interface does not have named attributes.

Best, Markus

Wrong repo, put it into the main one.
