Migrate to @oclif/core V3

[Amzani]

Why do we need this improvement?

We need @oclif/core V3 instead of V1:

• To enable the new Architecture feat: new CLI architecture (part 1) #1200 and more specifically be able to use, this kind of configuration

{
  "oclif": {
    "commands": {
      "strategy": "pattern",
      "target": "./dist/commands",
      "globPatterns": [
         "**/*.+(js|cjs|mjs|ts|tsx|mts|cts)",
        "!**/*.+(d.*|test.*|spec.*|helpers.*)?(x)"
      ]
    }
  }
}

• At some point V1 will be deprecated by @oclif

How will this change help?

This will enable us to have something like

Example for generate

.
└── generate
    ├── fromTemplate
    │   ├── fromTemplate.test.ts
    │   └── fromTemplate.ts
    ├── index.ts
    └── models
        ├── models.test.ts
        └── models.ts

Thanks to this, we will be able to have an easy CODEOWNER file
