[Feature]: Add shiki syntax highlighting plugin support

[hustcer]

What problem does this feature solve?

rspress seems to support PL syntax highlighting by prismjs at the moment, hopefully the Shiki plugin can be added as well. The advantage of supporting shiki is that prism may can't support syntax highlighting for some less common programming languages in the short term, but if it supports the shiki plugin, the corresponding syntax highlighting grammar can be applied to shiki as long as it has a VSCode extension. And the Nushell official site is currently using this solution!

What does the proposed API look like?

Something like this： https://vuepress.github.io/reference/plugin/shiki.html

Hey, any thoughts on this issue?
We may move away from VuePress and use rspress instead someday: nushell/nushell.github.io#1126
And this is the most important thing we care about. Thanks

Thanks for feedback. I think it's important to ensure the flexibility in code highlight solution. Currently the most difficult thing is that rspress does code highlight in runtime instead of compiled-time, in the meanwhile, shiki only supports compiled-time code highlight in most cases. So i'm going to solve the problem and add a @rspress/plugin-shiki to support shiki highlight in rspress.
