[NA]: Add GitHub Actions labeler configuration for automatic PR labeling

[JetoPistola]

Details

To make it easier, to filter pull requests, by labels, of focus in application:

• Frontend
• Backend
• Python SDK
• TypeScript SDK
• Infrastructure
• documentation

sync-labels: true # Remove labels if the file paths no longer match

See example, we didn't have any files that are Frontend | Python SDK | documentation, so they were removed automatically
