🛂 Adding code owners

[LVMVRQUXL]

📝 Description

We would like to create a .github/CODEOWNERS file in which @LVMVRQUXL will be defined as a default Code Owner for everything in the repository. Other Code Owners will be added in the future.

This change will be useful for automating the assignation of a new pull request's review, and for securing the important branches like main and api-reference that should require a review from Code Owners before integrating works.

See the GitHub documentation about code owners for more details.

✅ Checklist

• [ ] Create a .github/CODEOWNERS file with @LVMVRQUXL as a default Code Owner.
• [ ] Configure the main branch for requiring review from Code Owners.
• [ ] Configure the api-reference branch for requiring review from Code Owners.
