fix 'yarn start:website' command

[shoito]

When attempting to preview the website using the 'yarn start:website' command, the startup of webpack-dev-server failed.

❯ yarn start:website yarn run v1.22.19 $ webpack-dev-server --mode development --config webpack.website.ts /bin/sh: webpack-dev-server: command not found error Command failed with exit code 127. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

I successfully set up the webpack-dev-server by installing the 'webpack-dev-server' package and using the 'serve' option of 'webpack-cli'.

❯ yarn start:website yarn run v1.22.19 $ webpack serve --mode development --config webpack.website.ts <i> [webpack-dev-server] Project is running at: <i> [webpack-dev-server] Loopback: http://localhost:8080/ <i> [webpack-dev-server] On Your Network (IPv4): http://192.168.128.136:8080/ <i> [webpack-dev-server] On Your Network (IPv6): http://[fe80::1]:8080/ <i> [webpack-dev-server] Content not from webpack is served from '/Users/shoito/workspaces/diff2html/public' directory

Installing the webpack-dev-server package was necessary.
Without it, the situation would be as follows:

❯ npx webpack serve --mode development --config webpack.website.ts [webpack-cli] For using 'serve' command you need to install: 'webpack-dev-server' package. [webpack-cli] Would you like to install 'webpack-dev-server' package? (That will run 'yarn add -D webpack-dev-server') (Y/n)
