chore(project-config): reduce package size by removing Babel deps

[jtoar]

While pairing with @Josh-Walker-GM, he mentioned that @redwoodjs/project-config is ~3.2 MB, which seems bloated for a package that only contains a few functions. @babel/runtime-corejs3 and core-js alone comprise ~2.25 MB. So we could 1/3rd the size of this package by removing those, which entails swapping babel for esbuild like we tried in #8074.

Note that we have to leave the .babelrc.js file around for jest tests to work.

Probably a bit early but we could in the future add a default build options in the framework root. As a way to stay consistent with logLevel, platform etc.

@Josh-Walker-GM yeah if more packages end up building this way in the future I wouldn't mind
