Feat/migrate password reset token to app token table (#5051)

# This PR

- Fix #5021 
- Migrates `passwordResetToken` and `passwordResetTokenExpiresAt` fields
from `core.users` to `core.appToken`
- Marks those fields as `deprecated` so we can remove them later if we
are happy with the transition -- I took this decision on my own,
@FellipeMTX let me know what you think about it, we can also remove them
straight away if you think it's better
- Fixed the `database:migration` script from the `twenty-server` to:
```json
    "database:migrate": {
      "executor": "nx:run-commands",
      "dependsOn": ["build"], // added this line
      "options": {
        "cwd": "packages/twenty-server",
        "commands": [
          "nx typeorm -- migration:run -d src/database/typeorm/metadata/metadata.datasource",
          "nx typeorm -- migration:run -d src/database/typeorm/core/core.datasource"
        ],
        "parallel": false
      }
    },
```
The migration script wasn't running because the builds were not executed
- [x] Added unit tests for the token.service file's changes

Looking forward to hearing feedback from you
