docs: Adds project info command to troubleshooting

feat(docs): add project-info command to troubleshooting

Adds a section to the troubleshooting guide that explains how to use the `npx nuxt-users project-info` command to verify the database configuration and module setup. This helps users to identify and resolve database-related issues.

Additionally, simplifies the user creation example by removing the list users command.

The execute permissions are also updated on some scripts.
