Fixed imports of vite.config.extension.ts from projects

Path that was being used for fs.existsSync was not correct, missing .ts on
the end, so no extensions were being found or applied.

Import of extensions from correct staticPath triggers a TypeError:
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"

This is a known issue with vite importing from files in other packages
in a monorepo: vitejs/vite#5370

For now, using the workaround of importing via the relative path. Switching
to bun will apparently solve this.
