[chore] Update Makefile and best practices to match black selection vs ruff format (with doc fixes)

[jonpspri]

Summary

This PR updates documentation and configuration to accurately reflect the project's use of Black for formatting instead of ruff format.

Changes

• Best practices documentation: Updated linting section to reference black and isort instead of ruff format
• Documentation fixes:
  • Fixed typo: 'santitization' → 'sanitization'
  • Updated container base image reference from UBI9 to UBI10 (current: ubi10-minimal:10.0-1755721767)
• Makefile: Aligned linting targets with Black formatter usage

Context

The project uses Black as the code formatter (configured in pyproject.toml with line-length=200), not ruff format. This PR ensures documentation matches actual tooling.

Testing

• Verified changes align with actual Containerfile (line 51)
• Confirmed Black configuration in pyproject.toml
• Reviewed CLAUDE.md which documents: make autoflake isort black pre-commit

@crivetimihai Could you please re-trigger these tests? I'm suspecting the upload failed in the Great AWS Outage of October 2025 :)
