Introduce retry mechanism for npm install in CI/CD

This commit addresses occasional pipeline failures caused by transient
network errors during dependency installation with `npm ci`. It
centralizes the logic for installing npm dependencies and introduces a
retry mechanism.

The new approach will attempt `npm ci` up to 5 times with a 5-second
interval between each attempt, thereby increasing the resilience of
CI/CD pipelines.

This commit adds a new script `npm-install.js` with `npm run
install-deps` command to centralize npm dependency installation process
throughout the project. Separate testing of scripts to a separate
workflow.

It removes unused `install` dependency from `package.json`.
