[Feature request] add a bundler of `rspack/rsbuild` about vuepress-next

[Mister-Hope]

pr welcome

[Mister-Hope]

some updates to make things clear, we are looking forward for this if it supports most of the webpack loaders, but we are focusing on stable version and ecosystem now, and vite is fast enough to use. We would be happy to see anyone working on this, and I would like to help with any difficulty while developing.

i'm trying to make a bundler-rspack. once vuepress and @vuepress/theme-default is compatible, i'll make a small repo to show the results. Now rspack lacks persistent cache, and it'll be implementated in the future.

I just find it works well with vuepress and default theme,in development and production. here is my repo.

i only replace webpack keyword with @rspack/core, so the code is not perfect,and i will consider whether use rsbuild or rspack later.
