Spike: investigate removing src from pf npm packages

currently, the various packages published to npm pf-react all include the src directories which bloat the published pkg size to 6.05 MB https://www.npmjs.com/package/@patternfly/react-core?activeTab=code

it also does create scenarios where products could be importing from our src directories, then their own custom typescript configurations will result in compiled typescript different than the PF distributions. (and possibly build errors for the product)

Would it be possible to remove the src from the pf packages without requiring further breaking changes from the pf packages? If so, this could be possibly framed as a bug fix. That's the goal of this spike.

Jira Issue: PF-26

首先检查 pf-react 包的发布方式，并比较它们在 npm 中的内容，尤其是其中包含的 src 目录。检查移除 src 是否会影响现有的 import 或自定义 TypeScript 配置；完成标准是记录可行性、兼容性风险以及任何所需的软件包更改。
