Implement pre-commit and linting GitHub action

[Snuffy2]

This should not be merged until the project linting/formatting has been changed over to ruff

I recommend that you install pre-commit.ci into your GitHub account and allow it to run at least this repo (or all of your repos if you'd like).

• Go to https://pre-commit.ci/ and select Sign In with GitHub

This pull request sets up automated dependency updates and linting for the repository, introducing configuration files for Dependabot, GitHub Actions-based linters, and pre-commit hooks. These changes help ensure code quality and keep dependencies up-to-date with minimal manual intervention.

Automated Dependency Management:

• Added .github/dependabot.yml to enable weekly automated updates for GitHub Actions and Python (pip) dependencies, with a limit of 10 open pull requests per ecosystem.

Linting Workflow Integration:

• Created .github/workflows/linters.yml to run linters automatically on pull requests and pushes to main, including Python environment setup, caching, and pre-commit checks.

Pre-commit Hooks Configuration:

• Introduced .pre-commit-config.yaml specifying a range of pre-commit hooks for code quality (whitespace, file endings, YAML/TOML validity, large files, merge conflicts, shell scripts, spelling, and Python linting/formatting). Also configures automated autofix PRs and weekly updates for hooks.
