Update Dockerfile and configs to latest dependencies and fix deprecated Capybara field

[vanessuniq]

This PR implements several updates and fixes across our configuration files:

• Dockerfile Update: The bundled application version has been updated to 2.3.10 to ensure compatibility with the latest libraries and security patches.

• Capybara Field Deprecation: The deprecated [:capabilities] field in our Capybara setup has been replaced with :options to align with the latest syntax and avoid future deprecation issues.

• Node and Yarn Version Specification: The package.json has been updated to specify the versions of Node and Yarn we are using. This is to lock the project to stable versions and prevent inconsistencies across development environments.

These changes aim to improve our CI/CD pipeline efficiency and ensure a stable development environment for new features.
