When modifying config.ts imported outside of .vitepress folder, it is not hot reload

[lovetingyuan]

Describe the bug

I use the config file out of .vitepress, I just import it in .vitepress/config.ts

when I modify .vitepress/config.ts, hot reload works well, but I modify the outer config.ts, hot reloading does not work.

Reproduction

Just modify the outer config.ts, the page does not get update.

Expected behavior

I think vitepress should track the import modules graph in .vitepress/config.ts, and hot reload all of them.
