Pull request overview

This PR refactors the GitHub Actions workflow to optimize Docker image builds for linting tasks. Instead of building the linter image separately in each job, the workflow now builds it once in a dedicated job and pushes it to the GitHub Container Registry, with subsequent jobs pulling and reusing that image.

Key Changes:

• Introduced a build_linters job that builds and pushes the linter Docker image once
• Modified ruff_linter, ruff_format, and mypy jobs to depend on build_linters and pull the pre-built image
• Added repository name downcasing to ensure Docker tag compatibility
