Generalize and Centralize GitHub Workflows.

[beauremus]

Is your feature request related to a problem? Please describe.
I think we have an opportunity to generalize and centralize our workflows.

Describe the solution you'd like
I would like to see small workflows in other repos because they are using this repo and customizing it for their needs.
I think, at a minimum, we can have integration and deployment workflows for each language that we support.

Additional context
You can see that https://github.com/fermi-ad/extapi-acsys/blob/main/.github/workflows/cd.yml and https://github.com/fermi-ad/.github/blob/main/.github/workflows/flutter-deploy.yaml are very similar.

To help assess how we can generalize and centralize workflows, here are some clarifications:

• Supported languages: Could you confirm which programming languages we officially support across our repos? This will help us determine the scope for shared workflows.

• Frameworks and structure: Are all repositories following a similar directory structure or framework conventions? A consistent structure would make it easier to create reusable workflows.

• Deployment targets: Are all projects intended to be deployed to Kubernetes, or do we have a mix of deployment targets? This information is essential to define generalized deployment steps.
