chore: add CODEOWNERS file

Summary

Adds a .github/CODEOWNERS file to automatically suggest reviewers for pull requests. The file designates @saltenasl @jamesbhobbs @Artmann @andyjakubowski as default owners for all files in the repository, copied from the configuration in deepnote/deepnote.

Review & Testing Checklist for Human

• Verify that all GitHub usernames (@saltenasl @jamesbhobbs @Artmann @andyjakubowski) are correct and active
• Confirm these individuals are appropriate code owners for this VS Code extension repository

Notes

• This configuration mirrors the CODEOWNERS setup from the main deepnote/deepnote repository
• GitHub will automatically suggest these users as reviewers on future PRs
• The * pattern applies the ownership to all files in the repository

Learning: GitHub natively validates CODEOWNERS files for syntax errors and invalid team references, making external validation actions potentially unnecessary for small CODEOWNERS files where human validation is still feasible.

Timestamp: 2025-09-11T14:45:50.365Z
Learning: In CODEOWNERS files, m1so prefers specific paths over glob patterns when assigning broad ownership groups to avoid unintentionally granting access to other helm charts or configurations that shouldn't be accessible to the same group.
