chore: modify package.json and rollup.config

[ssi02014]

Summary

@cure53 👋 I found that package.json has the build commands umd, umd:min, es, and cjs set for each of them, and it runs the build through them.

The rollup.config.js setting allows you to do the build all at once. It's a minor difference, but it also makes the build go faster. 👍

I checked and the build results before the modification and after the modification were the same.

However, if you decide that this is not for you, you can reject it !! Thanks!!
