This PR replaces webpack with esbuild, as our bundler. The change leads to out-of-the-box ~5x improvement in bundling times, reducing the latency in watch-based workflows. Along with this a new development server (with live reload capacity) has been introduced to support watch command. [ci no changelog needed] ### Important Notes * workflow for checking docs has been removed because it was using outdated prettier version and caused troubles; while the same check is performed in a better way by the GUI/Lint job. * introduced little more typescript in the scripts in place of js, usually with minimal changes.
