Support for Dependabot [bot] in Repository

We would like to enable support for the `dependabot[bot]` in this repository to help keep our dependencies up to date. Dependabot automates the process of creating pull requests to update dependencies, making it easier to maintain the security and stability of the project.

**Motivation:**

By enabling Dependabot, we can:
- Automatically receive pull requests to update outdated dependencies.
- Support updates to GitHub Actions workflows, ensuring that CI/CD pipelines stay current with the latest versions of actions.
- Support updates to DevContainer configurations, ensuring that development environments are consistent and up to date.

**Request:**
- Enable Dependabot for dependency management in this repository.
- Configure Dependabot to check for updates on a regular basis (e.g., weekly, monthly).
- Define the acceptable versioning policy for the dependencies (e.g., patch, minor, or major updates).
- Enable Dependabot to update GitHub Actions workflows automatically.
- Enable Dependabot to manage and update DevContainer configurations, ensuring that the development environment stays in sync with dependency updates.

**Additional Information:**

- The repository includes GitHub Actions workflows and DevContainer configurations that should be monitored for updates.
- If any custom configuration is needed, please refer to the official documentation for [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-dependencies-updated-automatically)

This version includes specific support for GitHub Actions and DevContainers in addition to the usual dependency updates, making it clear that these areas are also a priority for automation.
