added regenerator-runtime as dependency for wp6.6 fix

[ajayadav09]

PRESS0-1793
Since the Wordpress6.6 r update emoved polyfills certain features are breaking, so to maintain the polyfills for the feature that was breaking added the regenrator-runtime dependency.

regenerator-runtime is a library that provides support for ES6 generator functions and async/await syntax in environments that do not natively support them. It's a runtime for the Babel plugin @babel/plugin-transform-regenerator, which transforms generator and async/await functions into a form that can run in older JavaScript environments.
