Fix UI tests: update Cypress config and test assertions

[imatiach-msft]

Description

This pull request updates Node.js compatibility across the project, improves E2E test reliability, and updates test dataset configurations to match new data. The most significant changes are grouped below.

Node.js version and compatibility updates:

• The Node.js version used in the CD workflow (.github/workflows/CD.yml) is updated from 16.x to 20.x.
• The CI workflow (.github/workflows/CI-typescript.yml) is updated to test against both Node.js 16.x and 20.x, ensuring compatibility with both versions.
• A workaround is added in webpack.config.js to address OpenSSL hash algorithm compatibility issues with Node.js 17+ and webpack 4, avoiding the need for the --openssl-legacy-provider flag.

E2E test reliability and compatibility improvements:

• In apps/dashboard-e2e/src/plugins/index.js, a custom webpack configuration is introduced to ignore CSS imports (using null-loader) and disable caching for Node 20 compatibility. The null-loader dependency is added to package.json. [1] [2]
• The E2E test for the Individual Feature Importance scatter chart is improved to reliably wait for chart rendering by querying DOM elements, making the test less flaky.

Test dataset updates:

• The number of datapoint values in several test datasets (Boston, Breast Cancer, EBM, IBM, and Iris) is incremented by one to reflect updated data, ensuring tests match the actual dataset sizes. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

Checklist

• I have added screenshots above for all UI changes.
• I have added e2e tests for all UI changes.
• Documentation was updated if it was needed.
