feat: simplify relative path

[HomyeeKing]

Description

just wondering if this format path can avoid circular dependency 🤔 or just personal preference?
also I found a circular denpency here
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/server/index.ts#L12
https://github.com/vitejs/vite/blob/main/packages/vite/src/node/config.ts#L9

I got stuck for a long time in this PR due to the circular dependency, but why this not crash the CI, is because just type import?
