Enable flake8-logging-format (G) linting rules via Ruff

[uvindusl]

Overview

This PR addresses issue #5792 by enabling and fixing violations of the Ruff lint rule G004 (logging-f-string). f-strings in logger calls have been replaced with lazy %-style formatting to improve performance and adhere to Mozilla's logging standards.

Changes

Refactored Logging: Converted f-strings to lazy interpolation in the following files:

    bugbug/code_search/parser.py
    bugbug/model.py
    bugbug/models/testselect.py
    bugbug/repository.py
    bugbug/tools/build_repair/agent.py

Thank you! Please fix the failing linting errors. Installing pre-commit will allow you to test that locally.

BTW. The PR enables all flake8-logging-format (G) rules, but this is fine. I will update the PR title to reflect that.

@uvindusl the lint task is still failing. Could you please fix it so we can merge this PR?

Also, consider running pre-commit locally; it'll help you catch errors faster instead of waiting on CI.
