Description

This pull request updates several GitHub Actions workflows to use newer versions of key actions and streamlines the dependency installation process. The main improvements focus on upgrading action versions for better reliability and security, and simplifying how dependencies are installed across jobs.

Workflow action upgrades:

• Updated all usages of actions/checkout from version 2 to version 4 for improved performance and security across .github/workflows/chromatic.yml, .github/workflows/node.js.yml, .github/workflows/publish-storybook.yml, and .github/workflows/publish.yml. [1] [2] [3] [4]
• Updated all usages of actions/setup-node from version 3 to version 4 to ensure compatibility with the latest Node.js features and security patches. [1] [2] [3] [4]
• Updated aws-actions/configure-aws-credentials from version 1 to version 2 in .github/workflows/publish-storybook.yml.

Dependency installation improvements:

• Replaced multiple yarn install steps with a single yarn install --immutable step in all workflows, ensuring that the lockfile is strictly followed and reducing redundant installs in subdirectories. [1] [2] [3] [4] [5]
• Removed unnecessary repeated installs in package subdirectories, simplifying workflow steps and speeding up CI runs. [1] [2] [3] [4]

Testing and build process simplification:

• Updated test and build steps to run directly after dependency installation, removing redundant install commands before running tests or builds in package directories. [1] [2] [3] [4]

These changes help keep workflows up-to-date, more maintainable, and faster.
