feat: Implement CI Pipeline for Linting

[torstenhoegel]

We need to set up a Continuous Integration (CI) pipeline for our project to ensure code quality and consistency. The CI pipeline should run linting checks automatically and fix any issues when possible.

Tasks:

Configure Linting:

Ensure npm run lint is set up to check for code style and quality issues.
Ensure npm run lint:fix is set up to automatically fix linting issues.

Set Up CI Pipeline:

Integrate a CI service (e.g., GitHub Actions, Travis CI, CircleCI) with our repository.
Create a configuration file (e.g., .github/workflows/lint.yml for GitHub Actions) to run linting commands on every push and pull request.

Expected Outcome:

Automated linting checks on each commit and pull request.
Consistent code style and reduced manual linting effort.

Additional Notes:

Ensure the pipeline is set up to provide clear feedback on linting errors.
Optionally, set up a badge in the README to display the CI status.

maybe use node --run
Let's use GA, I have GH pro so don't worry
also why not check if next.js build pass. But for that IDK if we need to up an db during the ci if we need db maybe not do it
