Add developer utilities for easier development

[pablo-schmeiser]

This pull request introduces several improvements focused on project configuration, code quality, and developer tooling. The main changes include adding and configuring pre-commit hooks, setting up formatting and linting rules for YAML and Markdown, enhancing the pyproject.toml metadata and dependency groups, and updating the Renovate configuration for automated dependency management.

Developer tooling and code quality:

• Added a comprehensive .pre-commit-config.yaml with multiple hooks for code formatting, linting, security, and typo checking to improve code quality and consistency.
• Introduced .prettierrc.yml for consistent code formatting, including support for Django templates and file-specific overrides.
• Added .yaml-lint.yml to enforce YAML style rules, such as line length warnings.
• Added markdown-lint.yml to enforce Markdown style and formatting rules.

Project metadata and dependencies:

• Improved pyproject.toml by adding license info, keywords, classifiers, and splitting optional dependencies into dev, tests, and docs groups. Also enhanced project URLs for better discoverability.

Automated dependency management:

• Updated renovate.json to include a detailed description, timezone, schedule, and custom grouping and automerge rules for different dependency types and improved labeling, optimizing dependency update workflows.

Ownership:

• Added @pablo-schmeiser to the .github/CODEOWNERS file.

Please fix up the changes to the appropriate commits. I will merge these commits as is in the main branch. It is important that they are complete on their own.
They belong to the commits Add Info and testing to pyprojects file and Add config for renovate bot.

Nothing a quick git reset --soft HEAD~1, two temporary commits and a git rebase -i master can't do :P
