fix: `exclude` is not working as expected.

[xieyhn]

Description

For example, my-app is the project I'm developing and its path on disk is /xie/__demo__/my-app/, when I use vite-plugin-pages it won't match any path because the default exclude option has **/__*__/**.

vite.config.ts

import { defineConfig } from 'vite'
import Vue from '@vitejs/plugin-vue'
import Pages from 'vite-plugin-pages'

export default defineConfig({
  plugins: [
    Vue(),
    Pages({
      dirs: [
        { dir: 'src/pages', baseRoute: 'pages' }
      ]
    })
  ]
})

So I think the exclude option here should be relative to my dir option, this PR resolve the problem.
