### What is this PR for? - Fix : https://issues.apache.org/jira/browse/ZEPPELIN-6052 Background --- Currently, the Zeppelin web application uses Webpack for its build tools. Webpack provides valuable features like hot module replacement (HMR) through webpack-dev-server, which greatly enhances the development experience by automatically updating the UI in response to code changes. Unfortunately, hot module replacement is not functioning properly, impacting the developer experience, particularly on the frontend (zeppelin-web). Resolution --- To resolve this issue, I updated webpack-dev-server from version ^3.1.10 to ^4.15.2. This update was selected as the latest version compatible with Webpack version 4. - Version Upgrade: Although I considered further upgrades, I chose the latest version compatible with Webpack version 4. I plan to migrate to Webpack version 5 incrementally. - Dependencies: The updated version 4.15.2 requires @webpack-cli/serve version ^1.2.0, which necessitated the installation of [email protected]. Consequently, I installed [email protected] too. - Configuration Changes: Due to BREAKING CHANGES introduced by the new version, modifications were required in the webpack.config.js to accommodate these updates. AS-IS ---  TO-BE ---  ### What type of PR is it?
