Use webpack to replace shell script and simplify the logic

[xcv58]

Move the shell scripts to webpack config. So that we can enable multiple things in following PR:

1. Generate the HTML file to avoid duplication: feat: support for npm #410 (comment)
2. Convert the project to yarn workspaces and add Turborepo support https://turborepo.org/
3. Remove the custom hash function and use webpack to generate the assets injects so it has builtin hash

@conwnet can you double-check whether the vscodeUnpkgProxyHandler and sourcegraphProxyHandler are still in use? Can we remove it from development mode?

github1s/scripts/serve-dist.js

Lines 36 to 43 in a5748f8

	const vscodeUnpkgProxyHandler = (req, res, vscodeUnpkgMatches) => {
	const publisher = vscodeUnpkgMatches[1];
	const restPartsPath = vscodeUnpkgMatches[2];
	const host = `${publisher}.vscode-unpkg.net`.toLowerCase();
	const target = `https://${host}/${publisher}/${restPartsPath}`;
	const headers = { host };
	proxyServer.web(req, res, { target, headers });
	};

The sourcegraphProxyHandler is no longer in use because sourcegraph api supports CORS now.
The vscodeUnpkgProxyHandler is still in use. @xcv58
