fix: browserslist query and rspack target

[fi3ework]

Summary

• Adding >= to browserslist query(e.g. Chrome 120.0.0 -> Chrome >= 120.0.0) as it's not valid before, we didn't notice that because SWC could accept that(playground), but the lightningcss tool in Rspack is using browserslist to resolve the query in advance and it will throw an error.

  

• Change the default syntax to not dead browsers last 1 version. However, this is not correct for all scenes. As the default syntax should be determined by current target (node or web), but in current implementation, the configs have an order which makes it hard to access the later from the former. We need a refactor IMO, to build some config builder like https://github.com/webpack/webpack/blob/main/lib/config/defaults.js. @Timeless0911 What's your opinion.
