Refactor CI workflows to use reusable test configuration

[jrhoads]

Purpose

This PR refactors the GitHub Actions workflows to improve maintainability and organization. It addresses the duplicated test logic across multiple workflows by introducing a reusable workflow.

Approach

The core of this change is the extraction of the test execution logic into a new, reusable workflow file (run_tests.yml). The existing dev.yml, release.yml, and staging.yml workflows are then updated to use this new reusable workflow. A new dependabot.yml file has also been added to automate dependency updates for pip packages.

Key Modifications

• Introduced run_tests.yml: A new reusable workflow that encapsulates the common testing steps, including environment setup, dependency installation, and test execution.
• Refactored existing workflows: dev.yml, release.yml, and staging.yml have been modified to use the run_tests.yml workflow, reducing code duplication.
• Added dependabot.yml: This file configures Dependabot to automatically create pull requests for pip dependency updates on a weekly basis, targeting the dev branch.

Important Technical Details

• The run_tests.yml workflow inherits secrets from the calling workflow, ensuring that sensitive information like AWS credentials and API keys are still securely provided.
• Dependabot is configured to create PRs for pip packages and label them accordingly.

Types of changes

• Refactoring (e.g. code restructuring, improving maintainability)
